Nitter complete color theory

Trichromacy

In Eye and Brain, test trichromacy by changing one controlled variable and comparing the evidence. Includes a layered explanation, active exercise, critique, vocabulary and internal Nitter connections.

Colour fact

Only three cone classes are needed to distinguish millions of colour experiences because the brain compares their overlapping responses.

Active color study

In Eye and Brain, test trichromacy by changing one controlled variable and comparing the evidence.

Estimated time: 75 minutes. The active exercise and optional knowledge check never gate navigation.

Scientific display limitation

Context scenes are illustrative rather than colorimetric evidence. Browser appearance varies across displays; print and CVD previews remain indicative.

• Previous: Central and Peripheral Vision

  Within Eye and Brain, build a working explanation of central and peripheral vision, keeping the model distinct from the appearance it describes.

• Next: Opponent Signals

  Apply opponent signals within Eye and Brain to a practical color decision, preserving both the reasoning and its constraints.
