Methods

addOpacity([double value = 0.5]) → Color
Makes the current color more transparent, by the given value, from 0 (total transparency) to 1 (no change). If value is not provided, it will be 0.5 (50% change). If value is less than 0, it's 0. If more than 1, it's 1. Makes it more transparent if percent < 1.
average(Color color, [double value = 0.5]) → Color
Makes the current color more similar to the given color, by the given value, from 0 (no change) to 1 (equal to color). If value is not provided, it will be 0.5 (50% change). If value is less than 0, it's 0. If more than 1, it's 1. Doesn't change the opacity.
darker([double value = 0.5]) → Color
Makes the color darker (more black), by the given value, from 0 (no change) to 1 (black). If value is not provided, it will be 0.5 (50% change). If value is less than 0, it's 0. If more than 1, it's 1. Doesn't change the opacity.
decolorize([double value = 1]) → Color
Makes the current color more grey (aprox. keeping its luminance), by the given value, from 0 (no change) to 1 (grey). If value is not provided, it will be 1 (100% change, no color at all). If value is less than 0, it's 0. If more than 1, it's 1. Doesn't change the opacity.
lighter([double value = 0.5]) → Color
Makes the color lighter (more white), by the given value, from 0 (no change) to 1 (white). If value is not provided, it will be 0.5 (50% change). If value is less than 0, it's 0. If more than 1, it's 1. Doesn't change the opacity.

Static Methods
