color filters for any vector of hex color values

Description

filters are based on rgb values

Usage

palette_filter(
  palette = palette_qualitative(),
  similar = F,
  greys = T,
  reds = T,
  greens = T,
  blues = T,
  dark = T,
  medium = T,
  bright = T,
  thresh_similar = 25
)

Arguments

palette	any vector with hex color values, Default: palette_qualitative()
similar,	logical, allow similar colours, similar colours are detected using a threshold (thresh_similar), two colours are similar when each value for RGB is within threshold range of the corresponding RGB value of the second colour, Default: F
greys,	logical, allow grey colours, blue == green == blue , Default: T
reds,	logical, allow red colours, blue < 50 & green < 50 & red > 200 , Default: T
greens,	logical, allow green colours, green > red & green > blue, Default: T
blues,	logical, allow blue colours, blue > green & green > red, Default: T
dark,	logical, allow colours of dark intensity, sum( red, green, blue) < 420 , Default: T
medium,	logical, allow colours of medium intensity, between( sum( red, green, blue), 420, 600) , Default: T
bright,	logical, allow colours of bright intensity, sum( red, green, blue) > 600, Default: T
thresh_similar,	int, threshold for defining similar colours, see similar, Default: 25

Value

vector with hex colors

Examples

require(magrittr)
