Our new house is going to have timber windows. On the outside they will be stained grey to go with some slate sills. On the inside I would like them to match the oak floors. I have just been to see one of the local joinery companies in Lerwick and I seem to have a choice of a reddish hardwood or pine. I am not convinced that the hardwood will look OK with the oak floors and I am not sure about its provenance / sustainability either. If I go for softwood, then I think that its natural colour will be too light for the oak floor. Can I stain it so that the colour matches the floor?
