The red tint is obvious, but it's red saturation along with other colors. Never had much luck with tweak.
I used this:
Code:
ColorYUV(cont_v=-130,off_v=-4)
ColorYUV(cont_u=-40)
SmoothTweak(saturation=1.4)
Then I raised mid levels a bit with ColorMill. The sample looks a little dim and grimy. Before's and after's:
There's still a problem with blue/green. Blue has a bad midrange spike, and in a blue histogram is shaped like a left-hand "wedge".
You can't just reduce blue saturation, everything turns green.
The green has too much blue because of it. White arrows point to the blue spike problem. Maybe masktools can fix that?
