your lovely kitchen seems to recede into the walls as in my opinion there is not enough contrast and wevet may have the same issue.....so personally I would choose a stronger colour....don't forget you won't see much as most of the wall is covered with cabinets. Also with a window and French doors and a pale reflective floor it will be reasonably light. Choose a colour that you like that is used elsewhere in the house that you like and it will lend continuity. how about Farrow and Balls India Yellow?

Personally I wouldn't go with a yellow splash back. Not because it wouldn't go but more that you already have enough of that accent colour around the room, over do it and it can look forced. There is a fine line between getting the balance right were it looks classy and going over board to the point it looks naff. Personally I would either go for a splash back that is colour matched to the walls or a smoked mirror. You are limited in some ways because it appears there wasn't any forward planning with regards to splash backs. Any splash backs would need to be confined to the width of the extractor because your curved wall units won't open otherwise. They would have to be packed off the wall if you wanted to go full width splash back. I would recommend a durable matt paint in the kitchen. Good quality ones will withstand washing without polishing up and showing tell tell marks where they've been washed. Little Greenes Intelligent Matt is perfect for this and is our choice of paint when not using any further splash backs above the granite upstands. I understand a colour matched glass splash back or smoked mirror may seem like the safe option and boring to some, but there is no point in being brave just for the sake of it. You've got plenty of other points of interest in the room with regards to colour without having to push it too far. Let the kitchen itself be a subtle canvas to show off other items rather than fight with them for attention would be my advice.

Never thought about painting the frame black so that could work. I used to have a black door but it showed up any marks too easily (worse than white!) and also, it's a ugly dated door so I don't want to highlight it really. Can't afford a new one but will cover the glass with etched film which will look better than the current glass. I was going to hack them all out and re putty new pieces in but it will just take too long and I have to much to do in the house, ha ha.

Bronze Mirror will look very classy and will make the room feel more spacious. My no 1 in almost every kitchen I design. (Jo)
