Multiple choice

What is the relationship between color temperature and the perceived warmth or coolness of a light source?

  1. Higher color temperature corresponds to warmer light.

  2. Higher color temperature corresponds to cooler light.

  3. Color temperature has no relationship with the perceived warmth or coolness of a light source.

  4. The relationship depends on the type of light source.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Higher color temperature corresponds to cooler light, while lower color temperature corresponds to warmer light. This is because higher color temperature represents a higher energy level, which is associated with shorter wavelengths and a bluish-white appearance, while lower color temperature represents a lower energy level, which is associated with longer wavelengths and a reddish-orange appearance.
