                            A modern, interactive and smart palette for Adobe Photoshop CC.
While designed for professionals colorists, we see no reason it shouldn't be enjoyable to use by all.

Dynamic Palettes are of the same family, but unlike Dyamic Swatches, they're directly under your control. You always have the option of allowing the palette to generate ranges automatically to or from your current color. They can, however, also be locked down and even controlled independantly.
There's also a new Gel function! - replicating Gel light source filters to help change your colors through different light conditions.
There's even a bonus gradient generator allowing you to save your ranges as gradient presets with a single click.
In short.. a comprehensive palette toolbox for any professional colorist.
