HUD Color Picker

Question

the HUD color picker is pretty useful, but it's buried under a complicated shortcut (shift+alt+ctrl+right button) all held down at the same time. When all buttons are released, the color picker disappears.
Here's my question: when the picker is visible, the saturation and value automatically change as you simply hover the cursor anywhere within the 'square' portion of its window. (The color ring is on the outer edges, and I'll get to that).  You don't need to click on the picker to choose a new saturation or value; you only need to hover ontop of the new saturation/value and then release the buttons when you're ontop of the saturation/value that you'd like to select. As you hover within the window, the saturation/value is automatically updating in real time depending on what location your cursor is ontop of within the square portion of the window. But the problem is that when the picker first becomes visible, the cursor is automatically placed directly in the center of its window. So when you hover the cursor to the outer edges where the color ring is (in order to shift the hue), it is also shifting the saturation/value as you pull the cursor from the center of the HUD window over to the ring on the outside. Hope this makes sense.
How do you use the HUD color picker to shift only the hue without affecting the saturation/value?

Answer 1

well, I've managed to re-map the entire process since starting this thread (using AutoHotKey). Here's what I do now:
hold down 'b' on the keyboard (hold it down, not press+release) and the standard photoshop color picker window appears. I can now choose my color, hue, and saturation (as normal). No worrying about values or saturations shifting; this is the default color picker window.
then, release 'b' and the color picker window disappears. This is essentially *identical* to the HUD color picker function, except that there are 2 improvements:
-you no longer need to press 4 keys to get it to appear (shift+ctrl+alt+right button) - you only need to hold down 'b' on the keyboard
-when you release 'b', the color picker window disappears, exactly the same way the the HUD color picker does.
The only drawback I would suppose, is that's it's a fraction slower - not *quite* as fast as the HUD color picker, but that would be nitpicking. Still works fast, and great.
But with the HUD color picker, I would still like to know if there's a way to keep the same sat/value while only shifting the hue... i find it hard to believe that Adobe implemented this HUD color wheel with such a major flaw... I'm thinking it's got to be something I'm doing wrong
