Details

This data contains a list of linear/sequential color gradients generated with a multi-hue technique similar to that used by RColorBrewer to expand the visual clarity of a linear single-hue color gradient. Colors were chosed to avoid common color-blindness problems, and to maximize visual differences between color gradients.

The colors in jam_linear are designed so that colors in jam_divergent can be chosen for consistency. For example linear color gradient "firebrick" can be used to show coverage values, and "skyblue_firebrick" can be used to show coverage difference from control, and in both cases the maximum color is "firebrick".

These linear gradients are designed with a white background color. Note the jam_divergent colors are designed with a black background, intended to help indicate that these colors are divergent.

In general, there are seven warm color tones, and seven cool color tones. Visual distinction is only expected between warm and cool color tones, and is not distinct within the same color tone.

Each color is named by the closest corresponding R color:

  • firebrick

  • orangered

  • tomato

  • sienna

  • goldenrod

  • gold

  • skyblue

  • dodgerblue

  • royalblue

  • slateblue

  • orchid

  • magenta

  • maroon
