does godots color have this mode?

sort of. you can create swatches to re-use often utilized colors, which is kinda like the aseprite palette in that regards.

however, unlike aseprite, it is not a palette - if you change a color swatch, the places where you used it won't magically change.

otherwise, you'd need a reason why you'd want a palette selector like aseprite in godot.

it is not a painting tool, after all.
