Colours

Those are rgb values. So the 0 0 for the first two simply mean no green, no blue. The 255 for red is as red as it can be using the 0 to 255 value range. Change the two zeros to a number above zero and the red will become darker, change all of them to 255 and the guidelines will be rgb black.

Create a rectangle. Pull up the color editor and set it to rgb. Play with the three values. That would be the effect on the guideline colors if set identically.

Should 255,255,255 not be white and 0,0,0 black?

Heh, heh. Yep. Got it a little backwards, eh? Well, having white guides would be interesting...

Oh. And one other thing.

If, like me, you have the Units in the Options dialog for Xara products set to percentage, it is weird to play with RGB (now, when the heck is Xara gonna fix that business?). So one may need to change units to the 255 scale.
