Usage

Include :color_utils under dependencies in your mix.exs file.

defp deps do
  [{:color_utils, "0.2.0"}]
end

Convert HEX to RGB

iex(3)> ColorUtils.hex_to_rgb("#C8C8C8")
%RGB{blue: 200.0, green: 200.0, red: 200.0}

Convert RGB to HEX

iex(3)> rgb = %RGB{red: 200, blue: 200, green: 200}
%ColorUtils.RGB{blue: 200, green: 200, red: 200}
iex(4)> hex = ColorUtils.rgb_to_hex(rgb)
"#C8C8C8"

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}

Converting HSV to RGB

iex(7)> ColorUtils.hsv_to_rgb(%HSV{hue: 23, saturation: 15, value: 71.0})
%ColorUtils.RGB{blue: 153, green: 164, red: 181}

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}]

Calculate Triadic Colors

iex(8)> ColorUtils.get_triad_colors(%RGB{red: 255, green: 0, blue: 0})
[%ColorUtils.RGB{blue: 127, green: 0, red: 255},
%ColorUtils.RGB{blue: 0, green: 255, red: 127}]

Calculate Analogous Colors

iex(9)> ColorUtils.get_analogous_colors(%RGB{red: 255, green: 0, blue: 0})
[%ColorUtils.RGB{blue: 127, green: 0, red: 255},
%ColorUtils.RGB{blue: 0, green: 127, red: 255}]
