Hue palette (discrete)

hue_pal(h = c(0, 360) + 15, c = 100, l = 65, h.start = 0,
  direction = 1)

Arguments

h

range of hues to use, in [0, 360]
c

chroma (intensity of colour), maximum value varies depending on combination of hue and luminance.
l

luminance (lightness), in [0, 100]
h.start

hue to start at
direction

direction to travel around the colour wheel, 1 = clockwise, -1 = counter-clockwise

Examples

show_col(hue_pal()(4))
show_col(hue_pal()(9))
show_col(hue_pal(l = 90)(9))
show_col(hue_pal(l = 30)(9))

show_col(hue_pal()(9))
show_col(hue_pal(direction = -1)(9))

show_col(hue_pal()(9))
show_col(hue_pal(h = c(0, 90))(9))
show_col(hue_pal(h = c(90, 180))(9))
show_col(hue_pal(h = c(180, 270))(9))
show_col(hue_pal(h = c(270, 360))(9))
