Dwarf Fortress as a scale
Eleven steps from #1d0200, built by moving lightness in OKLCh and keeping the hue where it is. Every step is gamut-mapped by giving up chroma, never by clipping channels — clipping is what turns a light blue purple.

What is true of this ramp
- 10 of the 10 adjacent pairs differ by ΔE00 2 or more. Every step here is a step a reader can see.
- The tightest pair is 200 to300, at ΔE00 5.1.
- 2 steps had to give up chroma to stay inside sRGB — 50, 100. A wider display would show them more vividly.
- 4 steps clear 4.5:1 on white (700, 800, 900, 950), and 7 on black (50, 100, 200, 300, 400, 500, 600).
Harmonies from Dwarf Fortress
complement
the hue directly opposite, at the same lightness. #000e12 (+180°) — chroma capped by sRGB.
analogous
the two neighbours 30° either side. #1c0109 (+-30°), #150800 (+30°) — chroma capped by sRGB.
split complement
the two hues either side of the opposite, 30° apart from it. #000f0d (+150°), #000d1a (+210°) — chroma capped by sRGB.
triad
the circle divided in three. #001005 (+120°), #060822 (+240°) — chroma capped by sRGB.
tetrad
the circle divided in four. #080e00 (+90°), #000e12 (+180°), #11051d (+270°) — chroma capped by sRGB.
