All 9 plotly colormaps (7 sequential and 2 diverging) with side-by-side OKLCh diagnostics for lightness, chroma, hue, and colorblind safety.

• Blackbody (Plotly): sequential. Lightness spans 0.00–1.00, hue sweeps 256° from red to blue, and order holds under all three colorblind simulations.
• Bluered: diverging. Two arms meet at a pivot of lightness 0.42, hue sweeps 125° from blue to red, and order holds under all three colorblind simulations.
• Earth (Plotly): sequential. Lightness spans 0.27–1.00, hue sweeps 264° from blue to yellow, and order breaks under protan, deutan, and tritan simulation.
• Electric: sequential. Lightness rises monotonically from 0.00 to 0.98, hue sweeps 179° from magenta to chartreuse, and order breaks under tritan simulation.
• Jet: sequential. Lightness spans 0.28–0.97, hue sweeps 235° from blue to red, and order breaks under protan, deutan, and tritan simulation.
• Picnic: diverging. Two arms meet at a pivot of lightness 1.00, hue sweeps 157° from blue to red, and order breaks under tritan simulation.
• Plotly3: sequential. Lightness rises monotonically from 0.36 to 0.89, hue sweeps 63° from blue to magenta, and order holds under all three colorblind simulations.
• Portland: sequential. Lightness spans 0.35–0.87, hue sweeps 234° from blue to red, and order holds under all three colorblind simulations.
• Rainbow (Plotly): sequential. Lightness spans 0.35–0.92, hue sweeps 324° from rose to red, and order breaks under protan, deutan, and tritan simulation.
