How to check if something has the Color3 of {255,255,0] in starterPack?

I want to remove a text label in a weapon but i don't know where it is in the weapon. Can anyone give a hand? i'v also made it so that if you press "e" it will print out anything that has that color value.

mouse.KeyDown:connect(function(key) if key == "e" then "LINES OF CODE GOES HERE" end end)
