Armor previews?

I was wondering if there is a way to preview my armor at a certain color on each of its 3 parts , if the part has 3 sections to dye?

I wish there was a website for that

i tried using the change all costume color command but it just turns my character a whole load of different shades of green no matter what RGB values i put.

i believe you can do this with an dye amplue

ya but if ur on marketplace you cant preview the amps on the market to see if it is a match or not, making it possible for you to buy an amp that doesn't match

Edit: they should label the RGB values
