Root [Root App Request] - Tint Adjustment

[Haelous]

As the 'pink hue', 'red tint', etc issue with the AMOLED screens has been discussed ad naseum, I'll simply get to the point.

With root privileges, would it be possible to write an app that can adjust the tint (red/green balance) of the screen, regardless of what application you have open?

Isn't the red/pink a hardware issue related to the AMOLED display in low power mode?

But I digress - regardless of this, an application that could adjust tint, RGB, and/or CMYK would be useful in general.
