Black and white are not in the rainbow, but without them newspapers look weird. (That gets us to like 9?)
Light blue and dark blue are nice.
I give up. You win.
Without bright green and dark bright green our game boys would look ridiculous. So that’s found two more primary colours we need to keep.
Just one last colour to discover.
It's octarine, obviously
Without white there can’t be a rainbow. With black there is no rainbow visible.
