Source type: Colormap family

> All 11 ncar colormaps (9 sequential and 2 diverging) with side-by-side OKLCh diagnostics for lightness, chroma, hue, and colorblind safety.

- [NCL CBR drywet](https://colorcurio.us/colormaps/ncar.CBR_drywet): sequential. Lightness spans 0.32–0.97, hue sweeps 125° from yellow to mint, and order holds under all three colorblind simulations.
- [NCL CBR wet](https://colorcurio.us/colormaps/ncar.CBR_wet): sequential. Lightness falls monotonically from 1.00 to 0.24, hue sweeps 256° from green to blue, and order holds under all three colorblind simulations.
- [GMT drywet](https://colorcurio.us/colormaps/ncar.GMT_drywet): sequential. Lightness spans 0.33–0.88, hue sweeps 196° from yellow to violet, and order breaks under protan and tritan simulation.
- [GMT topo](https://colorcurio.us/colormaps/ncar.GMT_topo): sequential. Lightness spans 0.61–1.00, hue sweeps 360° from red to orange, and order breaks under protan, deutan, and tritan simulation.
- [MPL terrain (NCL)](https://colorcurio.us/colormaps/ncar.MPL_terrain): sequential. Lightness spans 0.40–1.00, hue sweeps 274° from violet to orange, and order breaks under protan, deutan, and tritan simulation.
- [NCL precip diff 12lev](https://colorcurio.us/colormaps/ncar.precip_diff_12lev): diverging. Two arms meet at a pivot of lightness 1.00, hue sweeps 187° from orange to blue, and order holds under all three colorblind simulations.
- [NCL precip 15lev](https://colorcurio.us/colormaps/ncar.precip2_15lev): sequential. Lightness spans 0.35–1.00, hue sweeps 329° from magenta to orange, and order breaks under protan, deutan, and tritan simulation.
- [NCL temp 19lev](https://colorcurio.us/colormaps/ncar.temp_19lev): sequential. Lightness spans 0.24–0.98, hue sweeps 186° from blue to orange, and order holds under all three colorblind simulations.
- [NCL temp diff 18lev](https://colorcurio.us/colormaps/ncar.temp_diff_18lev): diverging. Two arms meet at a pivot of lightness 1.00, hue sweeps 186° from blue to orange, and order holds under all three colorblind simulations.
- [NCL topo 15lev](https://colorcurio.us/colormaps/ncar.topo_15lev): sequential. Lightness spans 0.39–1.00, hue sweeps 271° from violet to orange, and order breaks under protan, deutan, and tritan simulation.
