Color Scheme E

Color scheme E

Color scheme E is a tentative color scheme to use for prime harmonics and potentially other intervals on the wiki. It aligns with various strong consensus opinions about the colors associated with primes (most notably, "7 is blue"). It is based on Hojo Minori's color scheme, in that it defines a gradient to be used throughout the octave and pulls colors from that.

The "neutral" color is to be used for background colors of e.g. text boxes, tables, etc.

The hex codes for Color Scheme E for the first 9 primes are the following. Note the extremely similar shades associated with 7, 29, and 31.

Prime	Color	Color (Neutral)
2	EEEEEE	888888
3	EA4335	BB4E45
5	59CD1F	5B963D
7	3C4AD8	4C55AB

19	1CCF9D	3B977D
23	E69138	B98147
29	375ADB	495EAB
31	2B7AE1	4961AB

Color scheme E.a3

This variation of color scheme E intend to give the primes in the upper region of the octave more distinct colors. It is the current color scheme used on the wiki.

Prime	Color	Color (Neutral)
2	EEEEEE	888888
3	BA2C00	C7634F
5	83FE35	8DCF56
7	2D00AE	654FC4
11	EEF400	CEC94F
13	7700A0	9D4FC3
17	58E3FE	59C3CF
19	50FFAC	59CE8F
23	D59100	CA9B4F
29	0007C8	4F5BC7
31	0C7BFE	4F92CF

Color scheme E.b1

Tristan Bay's prime harmonic color scheme E.b1 is similar to that of the original color scheme E. In this scheme, the base colors are all full-saturation except for the first and last ones, and all colors for primes up to 31 were picked manually. It also has a color palette for all 1200 cents in all 3 color modes.

Tuning error color scheme

A color scheme for tuning error in relative cents.

The magenta color is used for the perfectly in-tune interval, usually the equave.

Tristan's proposal

The relative error table colors are based off the ones from Vector's 2nd proposal.
