I checked this out using red and it worked, but I may have found the bug..
If you choose the gray from the 'Basic Color' squares on the Color Picker it doesn't work, if you use the slider at the right it does. The colour is shown as 192R/192G/192B in both cases, but it only prints when you set it with the slider.
Very odd!

Brian,
Thank you, waiting for a response by Bernard whether that is the solution.
Met vriendelijke groet, Ernst
