[Solved] AMD open source - anything comparable to CCC "Desktop Color"?

With AMD's proprietary drivers we get access to CCC which, among its other utilities, gives the user the ability to manually set RGB color values (gamma, brightness, contrast) for RGB channels for attached monitors.

I have three monitors whose color profiles I'm trying to match (Qnix Qx2710 monitors, no hardware based way to manipulate RGB). I know that using CCC is not the recommended solution - I have a colorimeter, and am still trying to generate ICC profiles that get the monitors to match one another. So far, this has not been fruitful.

In the past, on my Windows partition, I have used CCC to make adjustments so that my 3 monitors are close enough to each other for my needs - I'm not doing any type of photography or design work, I just can't stand having the same page(s) / windows look so drastically different across each monitor (it's particularly bad on white backgrounds).

I do not want to using AMD's drivers on my Arch install though. Is there any way to manipulate RGB channel values through the open source drivers (or some other means besides setting ICC profiles)? My searching so far hasn't turned up anything useful besides using ICC profiles.

you can adjust gamma and brightness with xrandr. there's also xgamma.
ICC profiles arch wiki page has a lot of information on the subject, but I assume you've already checked that.
