Dragon’s Fire as a scale
Eleven steps from #fc4a14, 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 50 to100, at ΔE00 5.8.
- 11 steps had to give up chroma to stay inside sRGB — 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 950. 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).
