This is the last of the features needed to make appearance management easy and convenient in OR. I don't know if I'll get it but I wanted to put in the request for posterity.

In the appearance panel, probably next to the existing color button, it would be great to have a pulldown of some sort that lets you choose from all the colors currently in use in the model.

For each entry I would show a color swatch and the HTML hex color code.

So, if a rocket were red/white/black, the pulldown would show those three colors in the pulldown.

The current color of the component would also be in the list, and shown as "selected".

I am not sure if "shine" parameter should be lumped in here. It is probably what you'd want, but it is probably not be worth the extra complexity... unless someone could figure out a UI for it that is clean and straightforward. Otherwise forget it.

The ideal functional implementation would probably be a label "Existing design colors", next to a pulldown. But that wouldn't fit next to the existing color button, and the idea is that you can set the color either by clicking the color button or using the pulldown, and in that case having them next to each other seemed nice. I guess you could add the new thing as another line in the appearance panel, don't know.

So I haven't figured out exactly what this should look like yet, but the function would be mighty useful.
