The 15 pages that link to Trichromacy, each with the reason it gives.

• Hermann von HelmholtzRelated: His color theory explained how three receptor signals can underlie many perceived colors.

• RGB color modelRelated: Three channels loosely parallel the three cone responses, though RGB values are not cone signals.

• Cone cellRelated: The three human cone classes provide the inputs for ordinary trichromatic color vision.

• Additive colorRelated: Three cone responses help explain why three light primaries can span many perceived colors.

• Color blindnessRelated: Typical human color vision compares signals from three cone classes.

• Photopic visionRelated: Human photopic color vision ordinarily combines long-, medium-, and short-wavelength cone signals.

• Color mixingRelated: Three cone responses underlie many three-primary mixing systems.

• RedRelated: Red perception depends on patterns across cone responses, not a dedicated red receptor.

• Yellow (color)Related: Yellow perception emerges from the relative activity of three cone classes.
