Po and qu can be used with intervals as well. A ruyo unison becomes a ruyopo 2nd. Neither the color nor the magnitude changes. | Po and qu can be used with intervals as well. A ruyo unison becomes a ruyopo 2nd. Neither the color nor the magnitude changes. | ||

Color notation merely renames ratios more conveniently, and strictly speaking, it only applies to just intonation. However, ratios are often used to loosely describe intervals in [[EDO | edos]], and colors can be used as well.

A more precise notation uses [[Ups and downs notation |'''ups''' '''and''' '''downs''']] (^ and v) as "virtual colors", inflections that always map to exactly one edostep. Ups and downs are used on the score just like color inflections are. Notes are named e.g. up C sharp = ^C#. [[Sharpness | Sharp-1 and flat-1]] edos don't require ups and downs. | ||
Unlike actual colors, virtual colors generally add up to something simpler, e.g. three of 22edo's ups adds up to an A1. Unlike actual colors, virtual colors combine with major, minor, etc. Intervals are named upmajor 3rd = ^M3, up 4th = ^4, downaug 5th = vA5, etc. | Unlike actual colors, virtual colors generally add up to something simpler, e.g. three of 22edo's ups adds up to an A1.
