- * @fileoverview An HSV (hue/saturation/value) color palette/picker
- * implementation. Inspired by examples like
- * http://johndyer.name/lab/colorpicker/ and the author's initial work. This
- * control allows for more control in picking colors than a simple swatch-based
- * palette. Without the styles from the demo css file, only a hex color label
- * and input field show up.
