Select Color: intensity/brightness not working as expected

I’m on W7 SP1 32-bit running 7.0.5. When I go to the color selector and choose “options” it gives me options to increase/decrease the intensity of all colors and increase/decrease the brightness of all colors. However, when I choose any one of these options all the colors seem to change to purples and reds. I lose yellows, greens and some blues. If I go back (increase then decrease) it never goes back to the original colors – until I restore to factory settings.

Anyone else experiencing this?

I was just trying to “soften” the default colors across the board.
