It expands on [[circle-of-fifths notation]] by using colored noteheads that indicate &#039;&#039;&#039;pitch-color&#039;&#039;&#039;. Additional inflections may be notated using arrows, similar to those of [[Kite&#039;s ups and downs notation]].<br /> <br /> Pitch-color is determined by a sequence of hues: (flatter) red, orange, yellow, green, blue, violet, pink (sharper). Yellow is generally treated as the &quot;middle&quot; color, e.g. for the [[reference pitch]].<br /> <br /> Catherino uses the following color schemes:<br /> * 24edo: 72edo subset (yellow and violet);<br /> * 36edo: 72edo subset (red, yellow and blue);<br /> * 53edo: (violet), orange, yellow, green, blue, (violet, pink)<br /> * 72edo: red, orange, yellow, green, blue, violet;<br /> * 106edo: 53edo superset with up/down arrows<br /> <br /> == External links ==<br /> * Catherino, Dolores.
