Oranges

Summary

Oranges is a sequential colormap from colorbrewer. Lightness falls monotonically from 0.98 to 0.40, hue sweeps 29° from yellow to orange, and order holds under all three colorblind simulations.

ColorBrewer 2.0 single-hue sequential 'Oranges' (9-class anchors).

Perceptual profile (OKLCh)

• Lightness: 0.975 → 0.405 (range 0.570, min 0.405, max 0.975); monotonic; midpoint 0.753
