It's in the kernel. And I know this kernel doesn't have it because in the change log on XDA it says Voodoo Color was removed.

The Dev's Explanation of Leaving Voodoo Color Out
"My current stance on VooDoo color:
I won't be adding it in anytime in the near future. While I see the benefit of it, it's something that I don't particularly like. I think the screen looks cleaner without it. Plus, I can't see how it could be affective across the board. All screen are different, so how can one fix work universally? Plus, those brightness tweaks that everyone talks about are included in here. They are part of an entirely different system. Voodoo was a color modification.
Now, in case anyone somehow missed it, v1.0.1 is posted. Here's a rundown:
-I've got 1.6GHz working. I added the code for it to properly step. It's running at 1.3v.
-I've stopped a process called Carrier IQ in the init.rc. This is, essentially, Sprint spyware used to gather data about your usage. TO ROM DEVS: You are going to want to remove the files from your ROM to make sure it doesn't start itself later. ACS has tested it and it doesn't seem to start again, but always on the safe side.
What's in the works:
-Adding a step/few steps between 1.2GHz and 1.6GHz. This should improve overall smoothness of the kernel.
-I'm going to up the voltage on 1.6GHz just a little. I *think* this is the cause of the vibration problem, but this is just a late-night theory.
I want to add that interactive seems to play well this kernel. I haven't played with it at all, but it doesn't seem to be ignoring mt minimum frequency settings like it was before. I don't know what's up with this. I suspect it has something to do with setting the defconfig minimum to 200MHz, but who knows. It doesn't drop to 100MHz, so it doesn't lock up... But that's just my experience. Because of this, I suggest interactive as your governor. I'll make it default for 1.0.4.
Thanks for your support and kind words, guys! It means a lot and keeps me going."

I have to go with his feelings on this, one thing I understand is how organic screens work and how an across the board tweak could not be consistent on all AMOLED screenes.
