Brush class
A Brush holds color information and describes how to draw the inside of a Shape or the stroke of a shape or a TextBlock or the background of any GraphObject.
A Brush must not be modified once it has been assigned to a GraphObject, such as the Shape#fill or TextBlock#stroke or GraphObject#background. However, a Brush may be shared by multiple GraphObjects.

Static Methods
-
darken(
String color) → String - This static function takes a color and darkens it by 20% in the Lab color space. This is a convenience function which calls Brush.darkenBy.
-
darkenBy(
String color, [num? fraction, EnumValue? mode]) → String - This static function takes a color and darkens it.
-
isDark(
dynamic color) → bool - This static function takes a color and determines whether it is "dark." Does not account for transparency.
-
isValidColor(
String color) → bool - This static function returns true if a given color string is well-formed for drawing.
-
lighten(
String color) → String - This static function takes a color and lightens it by 20% in the Lab color space. This is a convenience function which calls Brush.lightenBy.
-
lightenBy(
String color, [num? fraction, EnumValue? mode]) → String - This static function takes a color and lightens it.
-
mix(
String color1, String color2, [num? fraction]) → String - This static function takes two colors and mixes them together, using the (optionally) specified amount of the second color.
-
randomColor(
[num? min, num? max]) → String - This static function can be used to generate a random color.
