Image discoloration in 2.8.1

[Jim Ault]

I know that Photoshop manages color spaces and this information is embedded
in files that it generates.  Rev does not use this info (does not know how)
and so the RGB values will not be exactly the same, and each will be shifted
a different value.  I did some color work a year ago when I built a light
table in Rev and had to deal with this.  I used a quick workaround that I
don't recall at the moment, but the graphics gurus should be able to help
you here.

Since it involved color space management and rendering, I had to be very
specific in my solution.  One key for me was to chose the right color space
in Photoshop.  Again, I don't recall exactly what I did.

Hope this helps.
