I agree deepen the color, don't change it and yes art art art! maybe lessen the presence of the brick with the earlier suggestion of the metal cogs its and use traditional artwork pics/nature/paintings on the painted wall. I also like the idea to paint the part of the wall that juts out in a darker shade of the same color. Now you have lots to consider and lots to dismiss as well. Good luck and have fun

Consider going with tone on tone textured tiles. Keep it classical. Sometimes you can introduce a slightly darker contrasting grout color to accentuate the tile shape or design. The new trend is moving away from the subway tile look, it might date the kitchen in a short period of time. I would select your back splash tile before selecting the paint color. Paint colors I always select last, it is what pulls everything together.

I would use a brown glass subway tile and as for paint that will depend on what is in the rooms next to the kitchen a couple of pictures of the space and the arch would help.
