no setterinherited
hashCode → int: The hash code for this object.
no setterinherited
hex → String: Returns this as a hexidecimal string.
no setterinherited
hue → num: Gets the hue value of this color.
no setterinherited
inverted → LabColor: Inverts the values of this ColorModel, excluding alpha, in its own color space.
no setter
isBlack → bool: Returns true if this color is pure black.
no setterinherited
