That's really colorful! I came across a similar foundling at one point and took wide grossgrain ribbon to it as faux sashing. A large diamond in the center - a couple more on the outside, and at corners, a set at 90* makinng squares. It really changed it a lot! The bright colors found boundaries and glittered like stained glass.
I've also seen tops that were "too busy" to finish cut into 60* diamonds to form one big star against a solid background. It is a perfect base, but just needs an extreme light or dark to give your eyes a place to set. Strictly my own opinion. Your mileage may vary.
