Single Idea 4049

[filed under theme 12. Knowledge Sources / B. Perception / 5. Interpretation ]

Full Idea

A unique yellow experience may be evoked with monochrome light of 580nm, or a mixture of 540nm and 670nm. ..Our interpretation of colour experience is a highly idiosyncratic artefact of our visual system.

Clarification

'nm' are nanometres. 'Idiosyncratic' means unique and unpredictable.

Gist of Idea

The way in which colour experiences are evoked is physically odd and unpredictable
