Did someone tell you rainbows contain all the colors? Well, that's not true! It is missing a whopping 28% of colors!🌈

72% of all hues.

The space of visible colors is three-dimensional, and the spectrum is missing two dimensions (brightness and saturation). You can’t assign a percentage to that.

... also there are different choices for the scaling of the hue axis, so the percentage can change. This is also noted in the vid.
