## Summary

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

vispy preset 'spring' (magenta→yellow).

## Perceptual profile (OKLCh)

- Lightness: 0.702 → 0.968 (range 0.266, min 0.702, max 0.968); monotonic; midpoint 0.834
- Chroma: min 0.084, max 0.323, mean 0.165
- Hue: 328.4° → 109.8° (span 141.4°), path monotonic-cw; quadrants: magenta, rose, red, orange, yellow, chartreuse
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 84.4, mean/step 0.331, max step 0.584, smoothness 0.618, speed 0.331
