Tropical

Summary

Tropical is a sequential colormap from cmasher. Lightness rises monotonically from 0.48 to 0.90, hue sweeps 234° from magenta to cyan, and order holds under all three colorblind simulations.

Vivid tropical sequential.

Perceptual profile (OKLCh)

• Lightness: 0.477 → 0.903 (range 0.426, min 0.477, max 0.903); monotonic; midpoint 0.669
