It is because there is a coloring hierarchy: the Model Panel shows
the model color, but you can also set atom colors, whichoverrule and
hide the model color. As you found, Actions... Color and the "color"
command set the atom colors (otherwise you would not be able to make
different parts of the same model different colors).
If you already colored the atoms of a model, you can "uncolor" some or
all of them to reveal the model color using the command "~color".
Another way is to choose "Actions... Color... from editor" and then
