Single post in Sprite Discovery Discussion

I personally just don't quite understand why the color changes so drastically. Original Kalos sprites as far as I remember, had the same colors (or very, very similar) of the trims, because it was a DYE, not a part of pokemon. Recently in pokemon Home the color changes slightly, with shiny trims being lighter than the ordinary coloration (which I personally despise but it's a me problem) but a shiny Star STILL remains light-blue, a shiny Heart is still pink So, why a melan Debutante remains yellow-ish and a melan Pharaoh goes from blueish to dark-purple??? A Star goes from light icy blue to bright turquoise?? Can someone explain me the choice? I'm just kinda... confused
