Thanks a lot, now screen looks way better. Default settings on Franco kernel gives me terrible blue tint.

tried again after reading this, color is way too off as well, my eye is very sharp, often faced with very good display panel and I can see the colors very well. The suggested settings/values are way too off, franco's recommended values are much better but no offense, thanks for your effort!

aren't there going to be alot of variations in screens so there wouldn't be one set of 'perfect' settings for all?

That's exactly it. The variations in screens will mean that there will never be a "one size fits all" setting for the offsets and multipliers. I've had 3 GNs and all 3 have had different tints on it's screens.

Thus, it's better to take this as a guide and then tweak to your screen's needs. Personally, I only change the multiplier value and have it at "230... 230... 270...". Makes my stock yellowish tint disappear and I now have a whiter display.

can someone help me out?



i go to etc/init.d then i click new folder and name it 900colorcontrol-b50 (so etc/init.d/900colorcontrol-b50)

when i go to long press it in root explorer i do not get the "open with" options to select text editor

what am i doing wrong?

if it helps, im on franco 13.1, should i upgrade for this to work? and couldn't i just type the echo commands into terminal for multiplier values each boot?

a more in depth guide would be very helpful, i would love to be able to set at boot,

sorry im new to having an unlocked bootloader, came from a droid x

thanks

I'm sorry, but this is not entirely right.
Your recommended settings are correct for srgb as rgb working space - srgb however has a relatively low gamut compared to adobergb and ecirgbv2. Also, srgb should only be used by web designers, as it is also the native mode of every computer display. Photographers should use adobergb (native dslr color space) or ecirgbv2 (f.e. prepress retouching).

here are the official calibration targets for each color space:

srgb
Gamma 2.2
Color temp 6500k
Whitepoint 140cd

AdobeRGB
Gamma 2.2
Color temp 6500k
Whitepoint 120cd

eciRGBv2:
Gamma L*
Color Temp 5000k
Whitepoint 120cd

None of these settings are good for practical use tho (in prepress at least).
For best color accuracy, I recommend a color temp around 5700-5800k, 140cd and L* or 2.2 gamma, depending on your rgb working space (adobe or ecirgbv2).

photographers should use ecirgbv2 or adobergb, depending on what kind of work he or she does. ecirgbv2 is best suited for prepress use, as it offers the best color conversions to ISOCoatedv2.

General note:
whitepoint should always be adjusted to look like a white sheet of paper of your favorite photo paper.
color temp should always match the grade of white of your fav photo paper (bleached paper f.e. has a higher white point as yellow natural paper)

PS. make sure you have enabled "USB Debugging" (go to Settings->Developer options to double check).

PSS. This and OP's guide won't work on ROM's that has no init.d script autorun function!
