how2make these exactly?
Start with an
opaque white baseplate. Add layers of baseplates on top, you choose the color and quantity...
THESE MUST BE TRANSPARENT OR IT WILL FAIL (note that bottom color will be at the center of the circle). When you are done and everything, put a trans white layer of 1x1 plates on top.
Now look at what you've done.
