Exercise 3 solution

Sample answer:
In physics, a higher colour temperature means a bluer light, so a candle at 1,850 K is redder than golden-hour light at about 3,500 K. In everyday and artistic usage the words are reversed, so "warm" means a low kelvin number and "cool" means a high one (per the Color temperature article). Golden-hour light looks warm to the eye mainly because it is redder and softer than midday light at about 5,500 K, not because its number is smaller than a candle's.
The in-between 3,500 K label in the script's output reflects that it sits between the article's warm (2,700 to 3,000 K) and cool (over 5,000 K) groups.
