Heuristics for Color Distances and Locations

Description

• pick_colors() places each color into RGB space, clusters them with k-means, and returns the colors nearest each cluster center.

• color_order() reorders colors so that subsequent colors are far from each other in RGB space.

• color_distance() calculates pairwise distances in RGB space between colors.

Usage

pick_colors(hex, n)

color_distance(hex)

color_order(hex)

Arguments

Value

a character vector that is a subset of hex, or a matrix of distances for color_distance()

Examples

pick_colors(crayons$standard, 10)
color_order(crayons$standard)
color_distance(crayons$standard[1:4])
