Done to explore setting colors with sliders and some Math expressions. Additional features, should anyone wish to build, would be to convert to HSV space, and to produce Hex color codes as well.

To use colors, in the color controls of an element, replace the #XXXXXX hex code with this: rgb(255,125,45).

Two swatches are provided, since color combinations are more interesting than single colors. Swatches are draggable.
