is it normal that my LED colours seem to have multiple colours in them.. like example if i set the notification ligth to be orange ( with paranoid rom, but did the same on stock with lightflow) the light will be half light red and the other half will be yellow.. or green and blue if i want light blue.. it seems i have to mess around with the colours value (RGB) to get just one solid colour and not a mix of multiple colours..
this is hard to explain.. so if you know what i mean please let me know.. if not i can take a picture and upload them here!
Thanks
It's my understanding that although it IS an RGB LED, that doesn't necessarily mean that it will be able to recreate every color you could dream of. There's actually another thread here in the S3 section (Forget which part) where people are compiling a list of different Hex values of colors that turn out really well.

thing is is that im using ParanoidAndroid rom, and i dont see the option to add a hex value.. i can only pick a hue and slide the colour around ..
Well, in my experience with that, it seems to have a better color output for the LED if you don't have the saturation all the way up..... Say if you were shooting for a pure red color, have the slider down just a bit from as bright as it can get. Seemed like whenever i tried using that to set LED colors, if i had it all the way up, it had something else mixed in.... generally i think a bit more of a white color to it.

Does G2 track pad have color capabilities like the Nexus One trackball?
Don't think so but not too sure. I think I read somewhere that it turns blue when connected to a bluetooth headset, but someone tried it and it didn't change for them
Generally speaking, any white LED is actually an RGB LED, just because of the way that LEDs create light. I have no clue if that's the case here, but that's how it usually works.
So the file lights.vision.so refers to it as an RGB LED. It also gives an option to set the color. How do you modify that (or can you)? I have no clue. But that file at least refers to it as an RGB.
based on my experience theres different kind of LEDs some with multi colors some are sound sensitive and some are RGB only, therefore you cannot use purple on an RGB LED. BTW the lighting on the trackpad is the same as the one on the physical keyboard if you can change the trackpads color you could change the keyboards do, but you cant, i dont think you can change the color of that. btw the nexus one's trackball is an LED that changes color i dont know if its multi-color but yea the g2's trackpad doesnt have that

Uhhhh…I think you're distinctly unaware about how LEDs work. LEDs emit light of a certain frequency when current passes through them. "An" RGB LED is actually three LEDs, a red, green, and a blue, which together create white. However, by tweaking the brightness output of the individual LEDs that make up an RGB LED, you can create pretty much any color you want. That's how light works (as an aside, there really isn't such a thing as "white" colored light. You're simply seeing equal amounts of red, green, and blue).
So, generally speaking, if you have white, you have RGB (though they have developed "white" LEDs, they're more expensive to manufacture than simply making 3 colored LEDs). And if you have RGB, then you (probably) have the ability to create different colors.
Now, the possible kink in the idea here is that it may be that all three LEDs are run in circuit, so if you have one on, all three are on; you can't modify brightness individually. I don't know if that's the case here, but if it is, then there's nothing we can do. Someone who's done a teardown would probably be the only ones who would know.
PS, have you looked at a G2 before? Because the trackpad and the keyboard are on different parts of the phone. It's physically impossible for them to share a backlight. Not to mention the fact that the trackpad acts as a notification system, and flashes intermittently. Don't think you want your keyboard backlight doing that.
what i meant is the keyboard and trackpad use the same kind of LED, (not running on the same kind of circuitry. yeah someone could prolly tear it down and edit or tamper the LCD by themselves, i know what RGB is btw, i just did not know that white is possible. RGB = red green blue = different combinations of density on R or G or B = different color.
Any white led where you can see a bluish tinge is a white LED that isn't RGB. The trackpad I have a suspicion that its probably one of the newer LED's that's just a blue LED with the special coating that makes it white.

Just to share this with you guys..
With every display that I use, I try to have it calibrated and I was trilled that with the nexus I had so much control over the screen!! Never had a phone with so much control
You have here my results.
Just be aware that the "before" is with trinity kernel stock color scheme and I'm really grateful that his market tool and not to forget franco.kernel tool too,made possible for me to calibrate...
I used a 18% gray card to make sure white balance was spot on when converting the raw files into smaller jpg.
I did find that sometimes the changes did not apply so I did a double check by exaggerating the values when making the changes. Contrast was one of them..
On the graphs, the white dotted line is the reference
Only problem with this is that not all screens are the same so these settings will not work for everybody
My calibrated values
tint
red 200
green 169
blue 178
gamma
red 2
green 0
blue 0
disable dynamic contrast
contrast value 0
If you use franco.kernel tool
gamma 1.0
If you like image with more contrast, i would set it between -6 to -10
Very interesting and the before/after photos look good. Is there a problem with burn in?
Sent from my Galaxy Nexus
Looks a little red for me. Your results look great though.
The improvement in the color of the dog photo is drastic. Trinity kernel does come with the blue really cranked up for some reason. Looking good now.

for whatever reason trinity seems to be giving me better screen color, but im sure I could do the same with franco, anyways, my gamma settings are untouched, I found that modifying the color to these values makes the purple tint go away for me:
Red:135
Green:135
Blue:190
Trinity Contrast -15 to -25
If you look at the calibrated rgb graph, red is a few points bellow reference. And again if you look at the color temperature line it is a little above 6500k. It is normal for first reaction about red when actually your missing blue because almost every screen you are used too has to much blue on it..yet again there's the tint problem on a bunch of nexus too.. if I get my hands on one of them I'll post here the results
Edit: for you "red guys" try to invert the red with blue values
Red 178
Blue 200
BUT keep gamma the same.

you're welcome.
Outstanding. I was wondering if using my colorometer would work on the phone. Looks like I have a nice project for this weekend I need to revalidate my HT and PC too so might as well throw the phone in there too :O
Use hcfr and the color swatch app from the Market..
If you get stuck on gamma, don't sweat it too much.. I spent an hour trying to get it right, no luck with this screen. Colors are bang on though.
For those who don't know, 6500k is the reference color temperature. To most people it looks too red or even yellow, but it's what the whole publishing and photography world uses.

or you can install mxplayer,
get from here:
http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration
the mp4 version, extract it, goto to:
ColorHCFR Fields folder,
10% Grayscale folder
and use that files with mxplayer.
My gamma is 99% spot on. I go for 2.3x since with amoled screen the black mml is almost zero, you will not sacrifice shadow content and have a great contrast
I don't get it, how you use hcfr with android? I tried but I just can test my monitor (pc) =/ is there a guide or something?
the way I do right now is testing with http://www.lagom.nl/lcd-test/ and setting manually parameters on phone until it looks great.

you don't !! you use a laptop with the colorimeter connected to it.
your phone just plays the mp4 for calibrating your screen.

Yup, just like you use it to calibrate your HT screen. I run a long usb cable to my PC and use a DVD I burned with an ISO of test screens.
Thanks for the tips on test screens for the phone. saves me the time searching them out
I was searching on web I found that I need a meter, for that is the usb port right? (like spyder2 or EyeOne) mmm I was conecting my phone XD first time trying this tools. Now I understand what all this is about.
That looks that I will be doing this as usual =/ with my only 2 eyes :cyclops: meter XDD ohh wait that's just one of them xDD
well thanks for answer and that pic looks great. Right now I'm on CM10 and config my screen with their "advance" tool and comparing to the webpage I shared. That looks good too but I perceive a little bit reddish on dark colors. Thats so F******* better than blue one XD now looks like Super Amoled plus the contrast is pretty similar to SGS3.
Great post, thank you!
Excellent information, thanks!

I am on AOKP and every time I get a call the LED flashes a weird yellow/blue/green color and I don't know how to change it. I have flashed back to stock and it still happens. Light Flow can change the color but whenever I select a light blue or green color I still get a yellow tent. Has anyone else seen this?

I used "Samsung Blue: #ff1300ff". Even when I go back to a completely stock ROM the LED color on Boot has the same green/yellow/blue color. This phone was refurbished through AT&T so I'm starting to think this is why someone sent it back.

I already had to return one phone because the power button didn't work right. I don't think I'll be getting a refurbished phone again anytime soon.
Has anyone else seen this on an AT&T S III? I'd like to know if I need to return it.
What are all of the colors that people have found out can be make from the notification light? So far ive gotten green,blue,red,light blue, light green, and a weird light green with orange dot in the middle color.

Do you have White or Titanium ?
Lol, only three, R G B.
There is no light blue or light green, just your proximity sensor dimming the colour depending on your ambient lighting intensity. Dark room, light led, bright room, bright led.
To get custom colours, you need third party apps like Light Manager or Light Flow. However, after using Light Flow for a day, I can say, other than R G B, no colour appear to be prominent! But I've also heard this is a problem with the Grey units, but White ones, on white ones colours come out perfect it has been mentioned.

i thought LED can mix any color u like by RGB, depends on the kernel
btw, i just saw white, blue, green and red appeared on my note2
For those using Light Manager and/or Light Flow, which one has the best results on Galaxy Note 2? Any issues?
I'm reading A LOT of bad comments on Brazilian Play Store from S III users about Light Flow, and I'm afraid of messing up things here!
Don't be afraid of messing anything, if something goes wrong just uninstall the app.
And afaik, Light Manager is more consistent than Light Flow. It doesn't mess with your 'Accessibility' options. But I've seen that it drains battery in advanced mode, so better use it in Normal mode.

I was afraid because I read some comments related to an issue that messed up colors "forever". And something like eternal notifications until reboot. Of course, these could be solved with a full wipe.

I noticed this after I got my phone. All notifications are green including fully-charged, while Red is for charging. Does the LED really don't have a Blue Color?
Correct. The HTC 10 just has RG LED, no RGB.
Oh ok. That was helpful. Thank you.
This my main gripe with this phone. Was very disappointed to see such a simple feature missing.
On my old phone I used the Light Flow app to set different colours for all sorts of things. Simple things like being able to glance at the phone and know if it's a work or personal email was soo handy.
