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:

You can use the 2D interactive viewer to see the *modeled* effect of color-vision deficiency for a given luminance.

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.

Also in the notebooks collection, a 2D interactive viewer which you can also use to see the *modeled* effect of color-vision 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:
