ColorExtension

Library "ColorExtension"
Color Extension methods.

hsl(hue, saturation, lightness, transparency) HSL color transform.
Parameters:

• hue: float, hue color component, hue is a degree on the color wheel from 0 to 360. 0 is red, 120 is green, 240 is blue.
  
• saturation: float, saturation color component, saturation is a percentage value, 0 means a shade of gray and 100 is the full color.
  
• lightness: float, lightness color component, Lightness is also a percentage; 0 is black, 100 is white.
  
• transparency: float, transparency color component, transparency is also a percentage; 0 is opaque, 100 is transparent.

Returns: color

rgb_to_hsl(red, green, blue) Convert RGB to HSL color values
Parameters:

• red: float, red color component.
  
• green: float, green color component.
  
• blue: float, blue color component.

Returns: tuple with 3 float values, hue, saturation and lightness.

complement(primary) Complementary of selected color
Parameters:

• primary: color, the primary

Returns: color.

invert(primary) Inverts selected color.
Parameters:

• primary: color, the primary.

Returns: color.

is_cool(base) Color is cool or warm.
Parameters:

• base: color, the color to check.

Returns: bool.

temperature(base) Color temperature.
Parameters:

• base: color, the color to check.

Returns: bool.

is_high_key(base) Color is high key (orange yellow green).
Parameters:

• base: color, the color to check.

Returns: bool.

mix(base, mix, rate) Mix two colors together.
Parameters:

• base: color, the base color.
  
• mix: color, the color to mix.
  
• rate: float, default=0.5, the rate of mixture, range within 0.0 and 1.0.

Returns: color.

analog(primary) Selects 2 near spectrum colors (H +/- 45).
Parameters:

• primary: color, the base color.

Returns: tuple with 2 colors.

triadic(primary) Selects 2 far spectrum colors (H +/- 120).
Parameters:

• primary: color, the base color.

Returns: tuple with 2 colors.

tetradic(primary) Uses primary and the complementary color, + 60º to form a rectangular pattern on the color wheel.
Parameters:

• primary: color, the base color.

Returns: tuple with 3 colors.

square(primary) Uses primary and generate 3 equally spaced (90º) colors.
Parameters:

• primary: color, the base color.

Returns: tuple with 3 colors.

Release Notes:

updated description.

Release Notes:

added new functions:

shift_hue(base, angle) Shift the hue/angle of the provided color.
Parameters:

• base: color, base color.
  
• angle: float, angle to shift the hue of the base color.

Returns: color.

saturate(base, rate) Saturate the provided color by a rate of the difference to its maximum.
Parameters:

• base: color, base color.
  
• rate: float, default=0.5, rate to saturate the base color (the higher the saturation of the color the less the effect).

Returns: color.

desaturate(base, rate) Desaturate the provided color by a rate of the difference to its minimum.
Parameters:

• base: color, base color.
  
• rate: float, default=0.5, rate to desaturate the base color (the lower the saturation of the color the less the effect).

Returns: color.

lighten(base, rate) lighten the provided color by a rate of the difference to its maximum.
Parameters:

• base: color, base color.
  
• rate: float, default=0.5, rate to lighten the base color (the higher the lightness of the color the less the effect).

Returns: color.

darken(base, rate) darken the provided color by a rate of the difference to its minimum.
Parameters:

• base: color, base color.
  
• rate: float, default=0.5, rate to darken the base color (the lower the lightness of the color the less the effect).

Returns: color.

Release Notes:

improved some code and added:
color_to_hsl(base) Convert the provided color into HSL values.
Parameters:

• base: color, base color.

Returns: tuple with 3 floats.
