I'm redrawing a keyboard, it's basically black. and for the sake of precision I nee to use guide lines. The keyboard model I'm using is a jpg I've imported and locked on the workspace. So I using the Bezier tool to draw with and I need to setup guide lines over the jpg so I keep everything square and straight. The troubler is my guides are also essentially black... I can't see them. I thought I found the way to customize my guides but it doesn't seem to be universal. also the weight option doesn't seem to work.
Is there a way to customize the guides over-all? Universally?
