The toolbar is called "tool controls bar," the tool controls bar at the left is called "toolbox," and the toolbox at the right is called "commands bar."
If you asked me I'd say it's 3 toolbars. And why is palette not palette bar?
My guess that's because palette, the real world object, is something close to a bar itself, so it would be a bit of tautology. From the dictionary:
Palette: a thin board or slab on which an artist lays and mixes colours.
