Trying to find out how a green fill in a sort of concentric pattern would work with green in black.

Behold the fridge on which goes my art.

So this is really to find out what filling works well for these smaller shapes and what colors work well next to each other. In general I think that these wide variety is only distracting and the fills tend to draw attention away from the shapes and scales themselves. This is a one timer for sure.
Some days you just want to make some shapes and fill them with nice colors and gradients.
