This has been anti-aliased 2:1. I remember making this one. I had made alot of adjustments to the color dialogs while experimenting with other formulas. It didn't seem to be working out well so as a last resort I changed the formula a few times. This didn't improve things much until I clicked on Formula 6. I was surprised at how good this new color configuration suddenly looked with just that particular formula. I had never seen such a combination of plaster-white, reds greens and yellows
