TEMPERATURE CREATES RELATIONSHIPS
Warm and cool colours do more than determine whether someone has a “warm” or “cool” undertone.
Temperature creates visual relationships.
Warm colours tend to feel more advancing.
Cool colours can feel more receding.
But temperature is relative.
A red can be warm beside violet and cool beside orange.
A taupe can appear neutral until it is placed beside a strongly warm brown.
Therefore:
Temperature should be judged comparatively, not absolutely.
This becomes extremely useful in editorial makeup.
A cool taupe contour beneath a silver highlight creates a very different emotional world from a warm bronze contour beneath a gold highlight—even if the placement is identical.
The technique has not changed.
The visual language has.
