colorwheel: Visualize color palettes using a color wheel

In michaelmalick/r-chroma: chroma

Description

colorwheel allows you to easily visualize a color palette by plotting all hues for the specified chroma and luminance values using a color wheel

Usage

colorwheel(chroma = 100, luminance = 60, labels = TRUE, alpha = 1,
  fixup = TRUE)

Arguments

chroma	chroma value for palette
luminance	luminance value for palette
labels	logical, should degree labels be shown
alpha	transparency level defined on the interval [0, 1] where 0 = transparent and 1 = opaque
fixup	logical, should RGB value be corrected (see hcl

Value

colorwheel returns a pie chart showing the specified colors

Examples

colorwheel()
colorwheel(chroma = 50, luminance = 60)
colorwheel(chroma = 100, luminance = 75)
colorwheel(chroma = 100, luminance = 25)
colorwheel(chroma = 100, luminance = 0)
colorwheel(chroma = 0, luminance = 50)

par(mfrow = c(4, 3), mar = c(2, 0, 1.5, 0))
for(i in seq(0, 100, 10))
   colorwheel(chroma = i, labels = TRUE, fixup = TRUE)

par(mfrow = c(3, 3), mar = c(2, 0, 1.5, 0))
for(i in seq(20, 100, 10))
    colorwheel(luminance = i, labels = TRUE)
