Calculating differences between colors using the CIEDE2000 algorithm
gem install color_diff
Difference between two colors:
yellow = ColorDiff::Color::RGB.new 255, 255, 0
gold = ColorDiff::Color::RGB.new 255, 215, 0
ColorDiff.between yellow, gold
# => 11.584521223499245
Picking the most similar color from a list:
red = ColorDiff::Color::RGB.new 255, 0, 0
blue = ColorDiff::Color::RGB.new 0, 0, 255
yellow = ColorDiff::Color::RGB.new 255, 255, 0
gold = ColorDiff::Color::RGB.new 255, 215, 0
list = ColorDiff::List.new [red, blue, yellow]
list.closest_to(gold) == yellow
# => true
Building a map of nearest match colors from a finite palette:
red = ColorDiff::Color::RGB.new 255, 0, 0
black = ColorDiff::Color::RGB.new 0, 0, 0
dark_gray = ColorDiff::Color::RGB.new 80, 80, 80
maroon = ColorDiff::Color::RGB.new 128, 0, 0
list = ColorDiff::List.new [red, black]
palette = [dark_gray, maroon]
list.closest_to_map(palette)
# => { 'R255G0B0' => maroon, 'R0B0G0' => dark_gray }
