Static Properties

darken ↔ ColorFilter
Makes the color darker by the percentage specified in the first argument, or by 10% if no percentage is specified. Percentages should be specified as a float, e.g. an argument of 0.25 will result in a color 25% darker than the original. The darkening conversion is performed by adjusting the y component of the color in XYZ color space.
getter/setter pair
greyscale ↔ ColorFilter
Creates a greyscale color with the same perceived luminance as the source color (as given by the L* value of the color in the CieLAB color space).
getter/setter pair
invert ↔ ColorFilter
Inverts the color by flipping it along the red/green, blue/yellow, and light/dark axes.
getter/setter pair
lighten ↔ ColorFilter
Makes the color lighter by the percentage specified in the first argument, or by 10% if no percentage is specified.

The lightening conversion is performed by adjusting the y component of the color in XYZ color space.
