You may choose the most suitable colour for your windows. Coloured windows are not actually painted, but their profiles (sashes and frames) are covered with coloured laminated coating. Surface texture of laminated profiles is slightly grooved and resembles wood texture.
The least expensive and the most widely used are white windows with non-laminated profiles. The price of coloured windows is higher than the price of white windows. Window manufacturing time may differ depending on the chosen colour of the windows.
