Kry (pure)
Summary
Kry (pure) is a sequential colormap from colorcet. Lightness rises monotonically from 0.00 to 0.97, hue sweeps 110° from red to chartreuse, and order holds under all three colorblind simulations.
Perceptual profile (OKLCh)
- Lightness: 0.000 → 0.968 (range 0.968, min 0.000, max 0.968); monotonic; midpoint 0.583
- Chroma: min 0.000, max 0.240, mean 0.170
- Hue: 0.0° → 109.8° (span 109.8°), path monotonic-cw; quadrants: red, orange, yellow, chartreuse
- Endpoint temperature: null → warm
- Perceptual ΔE: total 128.5, mean/step 0.504, max step 2.516, smoothness 0.443, speed 0.504
Colorblind safety (ΔE under simulated CVD)
- Protanopia: ΔE total 87.2; preserves order: yes
- Deuteranopia: ΔE total 88.3; preserves order: yes
- Tritanopia: ΔE total 126.5; preserves order: yes
