>>17825946When you say "color differences", you're talking about how the Gold sprites on that site are a lot more dull than the Silver sprites, correct?
Well, the site made a mistake. Both games use identical color palettes. If you want my suggestion, just use the Silver sprites because those are the "true" colors.
If you want a more technical explanation, I'm pretty sure the Gold sprites use VBA's "Gameboy Colors" setting. This is supposed to make it look more like an actual GBC screen, which has extremely muted colors due to the lack of a backlight. Why that site used different settings for each game is beyond me. Someone should tell them.
