Palette Interpolation

There are several ways of interpolating between palettes. A palette is a list of 256 RGB colors.

• rgb interpolate pairwise as RGB values.
• hsv interpolate pairwise as HSV values, treating Hue as an interval from [0,6).
• hsv_circular interpolate pairwise, treating Hue as an angle, taking the shorter way around the circle.
• sweep interpolate by changing the palette values in order.

hsv_circular is also affected by hsv_rgb_palette_blend. if it's 0.0, then hsv_circular operates in hsv space only. if it's 1.0, then rgb. values in between blend between the two routes through color space.

The default is hsv_circular, as of v3.0.2. Before that it was hsv.
