Jumpsuit colors

Help me out here. I'm having a conversation with a guy on another board and he's telling me the reason GG Fett statue is Tan is because the ROTJ jumpsuit is tan. Since when? I know one is grey one is a blueish grey. Could someone verify, preferably with photos, differences in jumpsuits.

I assume some people can get the misconception of the 'tan' jumpsuit because in certain lighting the dirty weathering can give it that shade. But the ROTJ suit itself is a light grey.

if you see the real rotj you actually see that it is actually blue on the unexposed parts. very light blue, but it definately has a blueish tint. compared to the blue esb suit it is also much lighter. because of the weathering it definitely looks light grey. on screen it does look tan on some instances, but light grey is the accepted color right now
