From my impression of the Hoth vs X-Wing Lukes (don't have the X-Wing in hand), the Hoth figure is more of an olive skin tone, whereas the X-Wing Luke looks more like an actual tan -- more orangy dark. I noticed the same thing with the Hot Toys Han vs Hoth Han, the HT Han is almost an orangy tan look that seemed close to as dark, but since it had more tonal variation and represented more of a Tan look, it looks better--also, Han was tan in ANH and not so much on Hoth.
I think if Indy is the color of X-Wing Luke it will be okay, hopefully they just don't overcompensate with him given the darkness of some of their other figures lately.
