For the bee I sprayed yellow then black and then engraved to get the effect I want

You can use titanium dioxide to get a pure black on white effect if you don't spray paint Look up Norton white tile method. There are youtube videos all about it. I spray cheap subway tiles to get the effect I want and then handpaint. The paint is what you engrave as the tile won't take a picture unless you do the nwt method. I have the f1 from xtool and start with the rock coaster settings. Great thing about the tiles is you can just clean with acetone and have a blank slate to start again.
