Photographers use the terms "warm" and "cool" in exactly the opposite way physicists use the term.
Physicists are referring to thermal energy (specifically, the spectral emission of a black-body radiator) at some particular Kelvin, while photographers are talking about the yellowness or blueness of the light imparting a "fireside warmth" or "arctic glacier ...

By convention, yellow-red colors (like the flames of a fire) are considered warm, and blue-green colors (like light from an overcast sky) are considered cool. Confusingly, higher Kelvin temperatures (3600–5500 K) are what we consider cool and lower color temperatures (2700–3000 K) are considered warm. Cool light is preferred for visual tasks because it ...

Here is where some people get color temperature and thermal temperature confused. If the camera is set at 4500K, the picture taken with the 3000K incandescent light will be warmer. That is, it will be more on the orange/yellow end of the spectrum. The picture taken with the 6000K light source will be cooler, or more towards the blue end of the spectrum. ...
