I think it's a basic request(Or idea perhaps).
It's an extension that would work changing palettes.
(pixel palette changer) overlapping(active)
---((pixel palette changer))set rgb "active" (0,50,50) to rgb( 123,173,057)
Also. with backdrops, because create so many actives and slow down the game FPS is annoying.
(pixel palette changer) overlapping a backdrop
---((pixel palette changer)) set backdrop RGB (0,39,134) to rgb(032, 133, 230)
An image couldn't show better.
(please don't use the example background)
The extension could be like an active, with transparency and colors.
And an extension what does that would be great for water effects.
