System Information
Win8.1x64, 3x gtx580

Blender Version
2.79a

Short description of error
Noticed it in the Node Editor on Color Ramps, which sometimes are used for other than color purposes -
entering colors of "value" above 4.875, displays 4.875. It seems higher colors are accepted, however there's no (obvious) way of reading them.

Although (I assume) colors greater than 1.0 are used by some people, if those aren't actually supported, maybe they should be clipped? On the other hand having values above 1.0 is quite common with hdr etc., so being able to enter them directly without additional nodes and hassle of afterwards multiplication/gamma accounting should be possible, but then the limit then seems rather low.

Exact steps for others to reproduce the error

Open any color dialog, enter high Value.

The particular value of 4.875 is dependent on the setting of your ColorManagement Display device
This has been reported before in #40131
I'll merge this into #41287 as well and do some more reading up on this matter.

Thanks. It indeed is the reason for both the particular value and clipping.
