The colour you paint your house is a huge design consideration and long term investment.
But before you choose the colours for your house or wooden windows, you need to choose the quality of the paint. Exterior paints and preparation are dependent on weather conditions and will differ to the interior paint choices where bathrooms with a high moisture content are different to bedrooms. Do the research (enamel vs water-based, gloss vs matte), do the prep (undercoat, sanding, waterproofing etc) and never compromise on inferior paint quality. Then go ahead and have fun with the colours.
