Frage 8
Frage
Trichromatic colour theory: What did Young, Helmholz state about colour? (before it was backed up by physiology)?
Antworten
-
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
Frage 9
Frage
Trichromatic Colour Theory: Outline Hering's Opponent-Process Theory
Antworten
-
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
Frage 10
Frage
Why when looking at a pattern, do we see the image in the opposite colours when presented with a white screen?
Antworten
-
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
