Danger: red 43%, black 24%, orange 12%, …
Heller (1989)

Some of the differences in concept allocation are suggestive of real culture differences; for example: concepts like defeat, battle, thief, crime, and danger are all bad-strong-active (Osgood’s 3-factors) for Americans, Belgians, and Finns, but for the Japanese defeat, thief, crime, and danger are bad-weak-passive and battle is good-weak-active.

Osgood (1964)

The size of an angle can be determined by measuring the angle that two lines make with each other. This angle can be expressed in both degrees and radiants. The larger the angle, the more blunt it is. And conversely, the smaller the angle between two lines, the sharper.

The emotional effect of sharp corners differs according to the application. When it comes to utensils, sharp corners can be perceived as dangerous, they can puncture or cut.

Blunt/sharp is classified as a HEIGHT dimension parameter because a shape with blunt lines comes often with a thick shape, while sharpness appears most of the time in a thin shape. Compare the thick/thin parameter.

All countries: red.
Jung et al. (2018)

The devil is often depicted in green. The devil as a hunter for poor souls is an old motif, but the devil has only appeared in hunter’s suit since romanticism. In medieval images, the devil is still a cross between a snake and a dragon. Western demons usually have the toxic colours of green and yellow, or they are green and black.
