Sorry guys, if it's already reported.
The problem: Mediator, ColorMatrix settings. We should be able to configure the colors from 0.00 to 1.00. But it's only max 0.100, except for BlueY and BlueZ.

Not a big deal, because we can still edit the values in sweetfx.cfg, but I hope you guys will fix this in the next Mediator version.
