When it comes to choosing colours, the sky’s the limit. The warm light in a south-facing room will make everything appear more golden, especially on a sunny day. Pale colours will accentuate the feeling of light and space. Those with a rich (i.e. red or yellow) undertone, will maximize the sense of warmth while soft blues and greens will create a fresher feel. You can even use really cool blue or architectural greys - colours best avoided in other spaces - to create a very modern look.These colours balance the intensity of the natural light, appearing crisp and contemporary rather than cold and sterile.
When it comes to stronger colours, the only hue to treat with caution is red which is likely to dial up the sense of heat. Otherwise, the choice is yours but, as always, make sure you test samples of colours and fabrics in situ. The light, although abundant, will change significantly throughout the day - cooler in the morning and warmer later on - so it’s essential that you look at your samples at different times of day before making a final decision.
