Feature Request Color multiplier scalar or HDR color picker for UI elements

Hi Unity team,

Could you please add a color multiplier scalar (Intensity or something) or make the color picker HDR for all uGUI elements that can be tinted? I was thinking of creating my own shader starting from the default UI shader but then noticed there're 2 default shaders "UI/DefaultETC1" and "UI/Default" - which are 90% the same btw. The Button component has a Color multiplier, but even that's broken as the color is applied clamped in 0-1 range.

Please notice below how the 2x Orange tint is so much more vibrant than the 1x counterparts, which look dirty
