Trichromatic colour theory: What did Young, Helmholz state about colour? (before it was backed up by physiology)?

Wähle eine der folgenden:

  • We only need a few photoreceptors and can figure out any colour from their relative responses

  • We only need a few photorecpetors, which combined can make any colour

  • We need many photoreceptors and work out colours based on their relative responses

  • We need many photoreceptors each with it's own colour

Trichromatic Colour Theory: Outline Hering's Opponent-Process Theory

Wähle eine der folgenden:

  • Primary colours are in opposing pairs, see colours in terms of how much of one extreme it is

  • All colours are in opposing pairs, see colours in terms of how much of one extreme it is

  • Primary colours are in opposing pairs, see colours in terms of how one pair relates to other pairs

  • All colours are in opposing pairs, see colours in terms of how one pair relates to other pairs

Erklärung

Frage 10 von 16

1

Why when looking at a pattern, do we see the image in the opposite colours when presented with a white screen?

Wähle eine der folgenden:

  • We adapt to the colour presented, so the opposite colour is more strongly activated in relation

  • We adapt to the opposite colour, so the presented colour is more strongly activated in relation

  • The pupil absorbs the light of the original colours and reflect them back onto the white surface, and opposing colours are perceived to refraction

  • Our brain fill sin the gaps of what it thinks we should see, and because the presented colours have adapted, the opposing colours are the closest matched

Erklärung
