There are several companies which can print pictures on tile. This is fine for interior work but the kiln fired method is superior for outdoor use. If you have any particular photos or art, you can transmit images through email, ftp upload, or send pictures to be scanned. This allows wide flexibility for resizing to the installation of your choice and allowing photo editing.

I agree with Dytecture about using (and matching) the red for the accent wall. And I would strongly discourage using yellow--mostly because bright yellow and bright red in the same visual field remind too many people (including me) of the ubiquitous McDonald's colors.

Unfortunately all your options require custom work: It looks like you need an 18" corner cabinet. You will have to modify the last wall cabinet on the left. As I am eyeballing it, you should be able to cut the last cabinet in the middle and then shorten the left section to fit the space of the wall next to the door trim. It's an option that makes the area looks symmetric. Or you can install shelves over the sink. I would not recommend it because it will take the looks away. And the last option will be to remove the last cabinet, shorten it so it fits over the sink and install a single cabinet where the double one was. This will leave a triangle space behind the corner where the two cabinets will meet. You can block the space under it. Hope this helps!

I would recommend a soft gray...see photo below...
