Color has been changed by a filter

[Bleach]

When I try and change the color of text, for example to yellow, I get the message that "Color has been changed by a filter", and the resulting colour is very drab. i.e. from RGB255,255,0 to 149,149,0. How I change this? VS11.5Plus.

Found the solution:

To stop this, go into the Preferences dialog (Press F6 on your keyboard, or File menu>Preferences), and go to the Edit tab. Uncheck the first option Apply Color Filter--NTSC/PAL.
