What's the difference between perception and trichromatic?

Perception


Definition:

  • (n.) The faculty of perceiving; the faculty, or peculiar part, of man's constitution by which he has knowledge through the medium or instrumentality of the bodily organs; the act of apperhending material objects or qualities through the senses; -- distinguished from conception.
  • (n.) The quality, state, or capability, of being affected by something external; sensation; sensibility.
  • (n.) An idea; a notion.

Trichromatic


Definition:

  • (a.) Having or existing in three different phases of color; having three distinct color varieties; -- said of certain birds and insects.

Example Sentences:

  • (1) The results indicate that dichromatic and trichromatic monkeys differ only trivially on tests where performance is based on the contributions of non-opponent mechanisms, that the contribution of spectrally opponent mechanisms to the "brightness signal" is very similar in trichromatic and dichromatic monkeys, and that in increment-threshold discriminations where there are both chromaticity and luminance cues some test wavelengths yield superior performance for trichromats while others appear to favor the dichromat.
