Xenharmonic Reference:Color schemes
From Xenharmonic Reference

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 consensi 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.
| Prime | Color | Color (Neutral) |
|---|---|---|
| 2 | EEEEEE | 888888 |
| 3 | EA4335 | BB4E45 |
| 5 | 59CD1F | 5B963D |
| 7 | 3C4AD8 | 4C55AB |
| 11 | E0CB1D | A3983F |
| 13 | B33FD0 | 924FA3 |
| 17 | 1BA6EA | 3D88AC |
| 19 | 1CCF9D | 3B977D |
| 23 | E69138 | B98147 |
