Adding Multiple Color Parameters Together

Hi everyone,
I’m trying to make a character creator that has the ability to change the hue, saturation, and lightness in material parameters. I have created RGB color masks to select different aspect of the texture, but I don’t know how to put them together on the same texture to change only selected parts of the material.

I was able to change them separately, I can’t figure out how to add all them together. Thanks in advance!

Hey again,
I tampered with the material editor for a while and came up with a solution! For those who need to know, what I did was I made a few RGB masks for each piece that needed to be colored and for parts that are constants. I multiplied a grey version of my texture with a vector 3 parameter so that the texture detail will be retained. I then masked out the area i wanted so that only that area would be affected. I did this for all for different parts and then added them together at the end.

Hopefully this helped anyone!
