The .r3d will output an sRGB'ish image, assuming you select RedColor2
etc in the gamma settings

So, the viewer-process means you are apply a linear-to-sRGB node to the
already-sRGB image, so it looks washed out


Ideally you would select the linear-light gamma-setting, do comp'y stuff
then apply RedColor2's gamma as a viewer process, and maybe burn it into
Quicktime renders etc.. but to do that you need to determine the curve
it uses (simple bit of Python to create a ColorLookup by sampling two
Read nodes, one set to linear, the other set to RedColor2)

A simpler way would be to treat it like you have read in a sRGB JPEG:
after the Read, put a Colorspace node set to "in: sRGB", "out: linear"
