Please see tests for extensive usage.
Convert HEX to RGB
iex(3)> ColorUtils.hex_to_rgb("#C8C8C8")
%RGB{blue: 200.0, green: 200.0, red: 200.0}
Converting RGB to HSV
iex(1)> rgb = %RGB{red: 200, blue: 200, green: 200}
%RGB{blue: 200, green: 200, red: 200}
iex(2)> hsv = ColorUtils.rgb_to_hsv(rgb)
%HSV{hue: 0, saturation: 0.0, value: 78.4}
Calculate Complementary Colors
color = %RGB{red: 255, green: 0, blue: 0}
iex(6)> ColorUtils.get_complementary_colors(color)
[%RGB{blue: 127, green: 255, red: 0}, %RGB{blue: 255, green: 255, red: 0},
%RGB{blue: 255, green: 127, red: 0}]
