Drag the hue selector in the hue strip all the way to the right and all values zero out.
RGB Wheel, RYN Wheel, LCh Wheel don’t behave this way.
When I’m using this color selector dialogue, I don’t expect dragging left or right in the hue strip to affect saturation or brightness.
Shouldn’t hue stop at 360° (pure red) while the saturation and brightness values don’t change?
I’ll drag around in the square if I need to alter the saturation or brightness.
