Usage

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

Value

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

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

character indicating the distance metric to be used.

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.

Examples

find_similar_colour("#d339da")
find_similar_colour(c(124, 34, 201))

# suppress additional output
find_similar_colour("#85d3a1", verbose = FALSE)

# use Manhattan distance
find_similar_colour(c(124, 34, 201), distance = "manhattan")
