Picture of the Deadwood bar in Iowa City, where the marquee has the "W" missing so that it spells "DEAD OOD". Perhaps fittingly, above the marquee, a group of stuffies is posed in a window, appearing to stare forlornly at the pavement below.

find yourself someone who looks at you like Leon Draisaitl looks at Calvin Pickard after scoring an overtime goal

To design a color scale, I use dimensions: luminance, chroma, and hue. Color-spaces map these dimensions to (hex-valued) colors. Luminance drives a color scale, distinguishes a color from its background. Equal steps in luminance is not constant across color-spaces: observablehq.com/@ijlyttle/lu...

You can use the 2D interactive viewer to see the *modeled* effect of color-vision deficiency for a given luminance. observablehq.com/@ijlyttle/ch...

It turns out I can post *videos*, so trying this again Using the interactive 3D viewer can give you an idea of how a of how a color space collapses under a *model* of color-vision deficiency. observablehq.com/@ijlyttle/co...

Also in the notebooks collection, a 2D interactive viewer which you can also use to see the *modeled* effect of color-vision deficiency: observablehq.com/@ijlyttle/ch...
Two-dimensional view of Munsell color-space, at half-luminance, showing how it collapses under a model of color-vision deficiency, in this case, green deficiency.

For example, using the interactive 3D viewer can give you an idea of how a of how a color-space collapses under a *model* of color-vision deficiency:
