## Summary

Oxy is a sequential colormap from the cmocean collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

Designed for dissolved oxygen with saturated low/high anchors.

## Perceptual profile (OKLCh)

- Lightness: 0.240 → 0.774 (range 0.727, min 0.240, max 0.968); non-monotonic; midpoint 0.685
- Chroma: min 0.001, max 0.183, mean 0.061
- Hue: 27.3° → 89.0° (span 87.3°), path monotonic-cw; quadrants: red, orange, chartreuse, yellow
- Endpoint temperature: warm → warm
- Perceptual ΔE: total 145.8, mean/step 0.572, max step 27.062, smoothness 0.000, speed 0.572

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 133.8; preserves order: yes
- Deuteranopia: ΔE total 133.6; preserves order: no
- Tritanopia: ΔE total 131.1; preserves order: no
