The colors in the chart below come from a variety of sources. Color swatches are defined by using the six-digit hexadecimal code for the color. The colors are sorted
into groups of similar hue, saturation, and light value.
The sorting algorithm places
colors with hues closest together into each 8 x 8 grid and
then tries to position the high saturation and light values at the upper right position of each 8 x 8 grid.
This algorithm is not perfect because the set of colors it sorts are not at regular intervals, so the chips fall where they may.
If you want to see a chart of colors set at lock-step intervals, you can look at a table of hex colors generated at regular intervals of hue, saturation, and light.
Put your cursor over the color swatch to see the color name and comments if applicable.
The color names are descriptive and shouldn't be used to specify a color unless you are using the 16 named colors or SVG colors.
