filters are based on rgb values
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
