find_similar_colour(
  colour,
  distance = c("euclidean", "manhattan"),
  verbose = interactive()
)

Arguments

colour

a colour specified in one of three forms: a hexadecimal string of the form "#rrggbb" or "#rrggbbaa", a numeric vector of length 3 or a numeric matrix with dimensions c(3, 1), as it is returned by col2rgb(). Numeric values must be between 0 and 255.

distance

verbose

should additional output be produced? This shows the RGB values for the input colour, the most similar named colour and the difference between the two.

Value

a character of length one with the name of the most similar named colour.

Examples

find_similar_colour("#d339da")
#> [1] "mediumorchid"
find_similar_colour(c(124, 34, 201))
#> [1] "purple3"

# suppress additional output
find_similar_colour("#85d3a1", verbose = FALSE)
#> [1] "darkseagreen3"

# use Manhattan distance
find_similar_colour(c(124, 34, 201), distance = "manhattan")
#> [1] "purple3"
