Hue Saturation Value (HSV) = Hue Saturation Brightness (HSB) Colour Space

• A colour can be specified using R’s hsv() function that takes three arguments: hue, saturation, and value (brightness), all in the range [0, 1]

Hue Chroma Luminance (HCL) Colour Space

• A colour can be specified using R’s hcl() function that takes three arguments: hue [0,360], chroma [0,100], and luminance [0,100]
• This space is similar to the HSV space, however, in the HCL space steps of equal size correspond to approximately equal perceptual changes in colour
  • Note that the possible values of chroma and luminance actually depend on the specific hue; the ranges above are only indicative

Red Green Blue (RGB) Colour Space

• RGB is the built-in colour space. Instead of “manually” creating a #RRGGBB colour string, a colour can be specified using R’s rgb() function that takes three arguments: red, green, and blue (which, by default, all have a range of [0, 1])

wes_palette(name, n, type = c("discrete", "continuous"))

• name: Name of desired palette
• n: Number of colors desired. Unfortunately most palettes now only have 4 or 5 colors
• type: Either “continuous” or “discrete”
  • Use continuous if you want to automatically interpolate between colours
