Single post in Image errors!

Apologies in advance if this is intended and not an image error, but I noticed with the new Early Bird Natu sprites that the Weedles seem to be inconsistent? For lack of a better word?? (I literally don't know how to explain it so I'm gonna shove in some images) Regular: Shiny: The Weedle here is not shiny color, but normal. Albino: The Weedle is the shiny colors and not albino. Melan: The Weedle is shiny colors (I think? My eyes might be messing with me but the Weedle being held by the albino does seem to be a bit brighter) and not melan. Again, not sure if this is an 'image error' or exactly as intended, but with Pokémon like H.Purrloin/Liepard where the Spinarak changes color based on whether it's S/A/M I thought it might be worth bringing up? It seems to be the same with Xatu as well.
