[Q] Color Calibration on ICS?

---

Has anyone figured out how to adjust the screen colors under ICS yet? I used to use Chainfire3D's Nightmode to adjust the colors in GB, but that no longer works in ICS.

And before anyone asks "why?", I am a photographer and I view my photos on my TP. By default the colors are way off (~7200k white point).
Chainfire3D allowed me to adjust the colors where they were relatively close to 6500k across the board.

On my Epic 4g I use Voodoo Color, which is obviously for Galaxy S series devices only.

Maybe something like this could be ported?

Woohoo, I can confirm that Night Mode is working again under 4.0.4 and I am quite happy to have a color calibrated Touchpad again!

The only problem is that it also applies the adjustments to the recents thumbnails, thus doubling the correction (this would also be true for any screenshots).
