Do you have any ideas for what design to paint on my dresser in rainbow?

I found this awesome vintage sky blue dresser yesterday, and I’ve been needing a dresser. Psyched, I bought it. Super cheap too. So, I love rainbows, and I decided that, to make it pop, I wanted to paint a rainbow on it. but probably not RAINBOWS themselves, maybe one big rainbow stripe running from the floor on one side of the dresser up over the top down the other side. Or I was thinking of doing like a “lightning bolt” shape on top. Just something to add some pizzazz. I’m trying to think of different patterns or just anything that might look interesting. In rainbow. I’m not opposed to the idea of other simple shapes and pictures like a sun, or some clouds. OOH or the moon. So anything not too complex that incorporates obviously rainbows and possibly other things. I am not super artistic and I never paint, but I can do the basics well which is why I want to keep it simple. I just am kind of stuck for ideas which is why I was just gonna go with a rainbow stripe. I like that idea and if I can’t think of anything else I am fine with it, but I figured I’d throw it out there.

Oooh maybe some cool swirls?
