I’m looking at the currency block. Each box has a colored “drop shadow”. I spent a minute or so trying to figure out what the significance of the color is. Finally, I noticed that the color appears to cycle between cyan, magenta, and yellow. Is this a design element only, or do the colors actually have some meaning with respect to the symbol?

Purely cosmetic. In hindsight, probably unnecessary — but once you add color, it’s hard to stop
