hello,

Recently I've been using a lot of imported art and if possible, I would like to take a path and make it the color black when over a white background, and white when over a black background. Is this possible or is there an easy way to do it? 

for example I attached an image to explain. I made the diamond dark Gray so you can still see it over the black. 

I would like to make the diamond black, and where it crosses over the square, make it white. So it would be half black, half white. I hope that makes sense.

Hi @holtsie you can achieve this using Path Operations under the Path menu. To make the the specific area white:

• Select the diamond. (The diamond should be a path for this to work).
• Duplicate it by pressing Ctrl + D
• Deselect everything (Click anywhere else on the canvas), then select the diamond (the duplicated one)
• While the duplicated diamond is selected, select the rectangle and do Path > Intersection
• You now have just that area of diamond selected that is its own element. You can now change its color to your liking.

A couple of things to note regarding the condition that the diamond should be a path:

1. If the diamond is made of only strokes, first do Path > Stroke to Path
2. If the diamond is group, ungroup it first (Objects > Ungroup) and repeat step 1.

I think I found an easier way via Division giving the diamond is a shape and not a combined path:

Cut Path works as well - but you have to rebuilt the result by adding fill color and combine:

Combine with fillrule= Evenodd:

On last for now: LPE Boolean Operation. None destructive:

wow ok thank you!
