Kelvin → RGB/HEX. From candle-warm orange to north-sky blue, using the classic black-body curve fit — handy for lighting design, photo white balance, and warm/cool UI moods.
Color temperature describes the light a black-body radiator emits at a given temperature: lower is warmer (orange-red), higher is cooler (blue). In photography, 5600K approximates midday daylight and 3200K is studio tungsten; homes usually light between 2700–4000K. The conversion here is the classic approximation (Tanner Helland's fit) — plenty for design and lighting work, but not a colorimetry instrument.
