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
yea i agree with you that would be more effective, but let me check if there is a way to preview
cc_change_costume_color x y z
x = item slot (helm, gloves, etc)
y = color slot (primary, secondary, tertiary)
z = color code
there's already a thread on the hacks forum on this, but i'm too lazy to find and link it
