RingColorScheme class

Color scheme for painting progress rings.

A single color scheme will be used by a Ring. You can provide only one of the parameters. The order of precedence when multiple params are availble is ringGradients > ringColors > ringGradient > ringColor. When single color params(ringColor, ringColors) are provided if gradient is true then the end color for the ring will be brightened by intensity%.

When painting for unavailable nth number ring is required, the colors will be interpolated from the last element in the list. For subsequent rings where color is not available, when gradient is true then end color of previous ring is used as start color for this ring and end color for this ring is generated by brightening of start color. When gradient is false, start color is obtained by brightening previous ring color, then this ring is painted with same color For more explanation and examples, read property documentation.
