foreground_text_hsb

Since: 20210314-114017-04b7cedd

Configures a Hue, Saturation, Brightness transformation that is applied to monochrome glyphs.

The transform works by converting the RGB colors to HSV values and then multiplying the HSV by the numbers specified in foreground_text_hsb.

Modifying the hue changes the hue of the color by rotating it through the color wheel. It is not as useful as the other components, but is available "for free" as part of the colorspace conversion.

Modifying the saturation can add or reduce the amount of "colorfulness". Making the value smaller can make it appear more washed out.

Modifying the brightness can be used to dim or increase the perceived amount of light.

The range of these values is 0.0 and up; they are used to multiply the existing values, so the default of 1.0 preserves the existing component, whilst 0.5 will reduce it by half, and 2.0 will double the value.

return {
  -- This increases color saturation by 50%
  foreground_text_hsb = {
    hue = 1.0,
    saturation = 1.5,
    brightness = 1.0,
  },
}
