Functions

ciede2000_distance(color, other_color, opts \\ [])

Calculates the distance of two colors using the CIEDE2000 algorithm. See Tint.Distance.CIEDE2000 for more details.

from_tuple(arg)

Converts a tuple containing lightness, a and b into Tint.Lab struct.

nearest_color(color, palette, distance_algorithm \\ Distance.CIEDE2000)

Gets the nearest color from the given palette using the CIEDE2000 color distance algorithm.

nearest_colors(color, palette, n, distance_algorithm \\ Distance.CIEDE2000)

Gets the n nearest colors from the given palette using the CIEDE2000 color distance algorithm.

new(lightness, a, b)

Builds a new Lab color using the lightness, a and b color channels.

to_tuple(color)

Converts a Lab color into a tuple containing the lightness, a and b channels.
