## Color sequences
Easy ways of creating blends between colors.
Using the `rangeTo` operator:
```
for (c in ColorRGBa.PINK..ColorRGBa.BLUE.toHSVa() blend 10) {
drawer.fill = c
drawer.rectangle(0.0, 0.0, 40.0, 40.0)
drawer.translate(0.0, 40.0)
}
```
Or blends for multiple color stops using `colorSequence`. Blending takes place in the colorspace of the input arguments.
```
val cs = colorSequence(0.0 to ColorRGBa.PINK,
0.5 to ColorRGBa.BLUE,
1.0 to ColorRGBa.PINK.toHSLUVa()) // <-- note this one is in hsluv
for (c in cs blend (width / 40)) {
drawer.fill = c
drawer.stroke = null
drawer.rectangle(0.0, 0.0, 40.0, height.toDouble())
drawer.translate(40.0, 0.0)
}
```
## HSLUVa and HPLUVa colorspaces
Two color spaces are added: `ColorHSLUVa` and `ColorHPLUVa`, they are an implementation of the colorspaces presented at [hsluv.org](http://www.hsluv.org)
