either convert the colorspaces so they are the same for the pixes you want to 
mix with pix_mix, or simply stack the two images over each other in the Z axis 
[1] and manipulate the alpha [2] of the one in the foreground.

[1] for instance with [translateXYZ 0 0 -0.01]
[2] use [alpha] and [colorRGB]
