Saving out a color swatch

When opening up the color selector wheel with the list on the left hand side, I would like to Save a color or two to that list. Is that possible?

You can, sort of, but not, I think, from the color wheel thing- you can export color from a Rhino material parameter that uses a color though- drag the color swatch onto the desktop or into a folder - this will create a .rcolor file- this can be dragged onto an object in Rhino to assign a new material of that color- I do not know of any other way, so far, to interact with a .rcolor file- @andy can tell us…
