Plotly3

Summary

Plotly3 is a sequential colormap from plotly. Lightness rises monotonically from 0.36 to 0.89, hue sweeps 63° from blue to magenta, and order holds under all three colorblind simulations.

Plotly default 3rd colorscale; deep purple→magenta→pink.

Perceptual profile (OKLCh)

• Lightness: 0.359 → 0.888 (range 0.529, min 0.359, max 0.888); monotonic; midpoint 0.661
• Chroma: min 0.101, max 0.294, mean 0.238
• Hue: 264.8° → 326.4° (span 63.1°), path monotonic-cw; quadrants: blue, violet, magenta
