Setting RGB color values to 1 in Material asset Editor causes them to display as 191 and prevents them from being changed

Graphics - General

-

Setting RGB values in a material's color field (such as Albedo color in a material using the Standard shader) to 1 (e.g. R=1, G=1, B=1) causes each color channel that was set to 1 to report its value as 191. After that point, the values cannot be changed, even after new values are typed into the color panel. The alpha channel doesn't seem to be affected by this issue.

To reproduce:

1. Download attached project "ColorBugTester.zip" and open in Unity
2. In Project, window press Create > Material
3. Click on the Albedo color to open the Color panel
4. Set the R, G and B channels to 1
5. Close the Color panel
6. Reopen the Color panel by clicking the Albedo color again

Expected result: RGB channels still report that their value is 1
Actual result: RGB channels all now report that their value is 191

Notes:
- This issue reproduces on both Windows and OSX
- If you try to change those values, close and re-open the Color panel for the Albedo color you will see that they still report their values as 191
