Incandescent

Summary

Incandescent is a sequential colormap from tol. Lightness falls monotonically from 0.97 to 0.46, hue sweeps 169° from cyan to red, and order holds under all three colorblind simulations.

Sequential cyan-yellow-red.

Perceptual profile (OKLCh)

• Lightness: 0.966 → 0.460 (range 0.507, min 0.460, max 0.966); monotonic; midpoint 0.797
