       • Colours chosen should be soothing and relaxing to aid one to sleep comfortably
       • Orientation of the room. Rooms that have too much light during the day are warm and need cool colours while those that have very little light need warm colours to make them feel warmer
       • User of the room. Colours have feminine and masculine identity and thus a room for a boy may need to be painted differently from that of a girl
       • Existing decor. Colour of existing furnishings needs to be borne in mind so that the colour used in painting matches or contrasts well with the existing decor
       • Personal taste. The preferences of the user of the room are important in ensuring they feel happy and comfortable in the room
         (1 mark for statement, 1 mark for explanation, 2 x 3 = 6marks)
