Color macro usually means some sort of "fixed" settings. If you sweep through that, you'll go through a vast number of colors.
It's a setting I tend to avoid. I prefer setting my values using an RGB color chart. I'm more into setting scenes now, so I can installing pull up say a red or a light blue, for example.
And I bought 8 of the pro LED Par64's for the same reason. Doesn't take much to pop a club circuit, and doing mains, monitors, backline and lighting from a short set of circuits isn't fun!
