You can transform the colour of a patio you don't like by repainting the slabs. There may be just one colour of a two-tone patio that you want to remove, or you may want to change the whole area. Paint patios on a dry day, using masking tape to shield neighbouring slabs and surfaces from paint. Work out a route if you need to get back across to the house - you may have to paint it in stages. You can develop a pattern and use more than one colour for a really individual look . If you google your question you will get some more tips. Hope this helps
