Best color for "Change to Color" or "Replace Color"?
on Aug 28, 2017 at 10:16:41 pm

Hello all! I am shooting a little web project that involves cloning a bunch of characters wearing the same clothing, except I want them to have different colors of clothing. I'm going to use one of the effects mentioned above, but it is not immediately apparent to me what color I should use. It will be shot on green screen, so at first I was thinking of using blue for their outfits, but is that the best option? I will be shooting in 4K 4:2:2.

I'm just guessing that there is some intersection of hue, luminance, and saturation relating to chroma information that I should be aware of, since ultimately I desire to alter the hue and saturation without affecting luminance so that shadows and creases on the clothing is identical.

If you haven't done this stuff before, I STRONGLY recommend shooting test footage before you do it for real. See where the pitfalls lie before in too deep!

Blue is a good choice since you're going to shoot on a green screen.

Thankfully it's a home studio and I'm the only actor so it's relatively low stakes!

Glad to hear that, but I still say testing will save you a lot of potential grief.
Or it may affirm you got things right... and isn't that reassuring?
