Trimlight’s RGB system can produce ‘pure white’ by combining red, green, and blue at full intensity. You can also dial in any custom shade of white from cool to warm. Our standing recommendation for Tennessee homes: step out to the curb after dark and compare the temperature to surrounding Williamson, Maury, or Davidson County homes. Most Tennessee architecture — brick fronts, Hardie board, painted-brick — flatters at the warmer end (around 2700K).
