Would have asked this in the lewd version of this thread but apparently it doesn't exist? anyways.

I want to add a dong to one of my characters on vr chat since the base avatar doesn't come with one normally, I grabbed one and slapped it on and rigged, etc. but I'm having a lot of trouble getting the color on it to match the color of my avatar's skin, like no matter what I seem to try it's either too light or too dark and it looks really off. How exactly can I go about making the colors match perfectly so it looks naturally attached?
