NCL CBR drywet

Summary

NCL CBR drywet is a sequential colormap from ncar. Lightness spans 0.32–0.97, hue sweeps 125° from yellow to mint, and order holds under all three colorblind simulations.

NCL CBR drywet ramp (color-balanced).

Perceptual profile (OKLCh)

• Lightness: 0.347 → 0.318 (range 0.652, min 0.318, max 0.969); non-monotonic; midpoint 0.969
