Histograms of the range of luminance values for all unmixed hues of red, green, and blue.

Middle gray for our eyes is 18% gray for computer monitors (rgb(47,47,47) is L*a*b*(50.015), where L*.domain([0, 100])). The background color is the RGB value closest to L* == 50.

A 3-series histogram of red, green, and blue hue luminance distribution. The bars are z-axis sorted by height, and the graph is sortable by color, with animation.

Geometry is fun! Rotated x-axis labels calculated by input.

Move the slider to choose the angle of the x-axis labels.

Luminance Histogram for R, G, B Hues

This d3 histogram shows the range of luminance values (0 - 100) for all saturation levels of red, green, and blue hues, respectively. I've used opacity on a dark background to mimic proper color-mixing. D3 transitions provide smooth animation when showing and hiding individual histograms. The particularly interesting result here is that there is a much larger variety of light colors than of dark colors; if you were to choose an rgb() (or hex) color at random, bet on it being > 50 L*.
