Demo UI Browser to get your head around UI scripting. There are various other methods of getting UI element information, and if you don't fancy buying UI Browser once the demo expires, you could for example try this window analysis tool. Shortcat also looks interesting, although I haven't tried it myself.

The Color palette is a floating window, and while there may be some clever way of interacting with it that I'm not aware of, I opted for clicking relative to the location of a found image of the window title. You can see how I've set that up in the macro above. The easiest way to get coordinates is to use Mac's screenshot tool which displays coordinates when you click and drag; make a mental note of the numbers and press escape before it actually takes a screenshot. Alternatively, this macro will return relative coordinates. Trigger it, then click at the start point (in this case, the centre of the found image) and end point. It is set to display the values in a window, but if you enable the final group, clicking in the first coordinate field of the mouse click action (after the first two clicks) will paste the values in for you. I experimented with incorporating the coordinate grab into the Colours macro, but it seemed to be more hassle than it was worth.

nOb functions as a mouse emulator so clicking and dragging is easy. Set up a Quick Assignment in nAc (nOb's companion app) and set the location to the parameter you'd like to click and drag, while making sure the drag direction is appropriately set using the hardware switches. When you trigger this assignment with a shortcut, the mouse will jump to the parameter location and nOb will click and drag for you.
