Are there any projects or guides out there aiming to help calibrated your screen (as in colour management, not touch calibration)? The reason I ask is that there are a slew of apps, scripts, ROMs and kernels that provide different tools to help change different colour options. Many of them have in-build profiles, made by different people. I have a hardware calibration device and I have yet to find a profile that is anywhere near "good enough" (they are mostly horrendously bad). Maybe the included profiles are made for completely different devices than what they are included with, I don't know, but if no guide is out there -or a project to fix this- then there really should be.
Here's an example of a widespread profile used in more than one kernel(blue) versus stock(red):
