How to make a monochrome like this?
I don't know how to call this but how to make a monochrome like the one on bottom. The exclusion (white), but originally it doesn't overlap.
There's no trick or filter to making all-monochrome versions of your logo like this. I guess this designer simply drew the white contours so they would suggest the corresponding shapes in the colour version. Monochromising a logo can be quite an art.
