Thank you everyone, your thoughtful advice was very welcome. I'm attaching a photo as its all finished. I selected Olive Reserve for the splash back and painted the wall above it the same colour. As its a big room with lots of light and a large window it doesn't dominate. The glass is so easy to keep clean and I love the way it reflects the garden and light. Have to say though some people are stunned into silence when they see it, but as the cupboards and bench tops are quite bland I knew something bright was needed

i suggest that the best, not necessarily the cheapest option, is to have a glazier remove and replace with a "slab?" of plain glass splashback at the same time

When picking out colors I did have color consultant helping me and had the glass splash back winter calm picked out but now I would rather a tile. I was originally going for a sleek all white kitchen but decided to add the washed knotty laminex to the overhead cupboards but keep the rest white. I am having similar tone vinyl plank flooring through out kitchen and family room area. I was still thinking of a white tile???

Hi, I think this is a perfect solution. With obscure glass you get the light but not the view. This would look fine. Depending on your design of kitchen you could incorporate some art into glass. Obscure or privacy glass is the best option, or you could use frosted film for an economic solution.
