I know there is a good practical reason why people tile all the way between the hob and the extractor, but I really feel like a section tiled like this will look better. There will be shelves in line with the bottom of the hood to the wall both sides. Dissuade me.
If you like the clean look then do it with clear glass, paint the back the same colour as the wall. But do go up to the extractor, that's a really messy area and it will look rough really quickly.
