So the answer to John's question is "Black". Which tells us that it's the light entering our eyes that's the significant thing, not the physical properties of the strawberry or whatever object we're looking at.<br>
<br>
And the answer to my question is "Just one" (just one Red quality, etc.).<br>
<br>
Fine, so there's one Black quality that leads to the perception of Blackness, one White quality, one Red quality, one Blue quality, one Yellow quality, all of these are 'Primary Qualities', and colours like green, brown, grey, maroon, and even magenta can be explained by mixing together (which is what I presume 'subjectively bind' means) these different qualities in different combinations to produce the relevant experiences of different colours.<br>
<br>
Which means that there is no Green quality. All the green experiences we have are formed by combining a variety of the Blue and Yellow qualities, plus others as required. Similarly for purples, oranges, etc.<br>
<br>
And the Dark Red colour that I used previously must be a combination of the primary Red quality and the primary Black quality.<br>
<br>
I'm guessing that colour saturation (intensity) fits into this by varying the amount of White, and lightness by varying the amount of Black.<br>
<br>
So basically, our brains have a colour palette consisting of 'Spectrum' or 'Primary' colour qualities: Black, White, Red, Yellow, and Blue. This can produce all the millions of colours we can experience. Excellent.<br>
<br>
And this also means that each of these 'qualities' must have some mechanism to control the amounts of each that are mixed together to produce any specific colour experience. Each Quality must also have a Quantity.<br>
<br>
Good, that simplifies things considerably, and we only need five mysterious substances that embody these five Qualities, plus a way to control the 'dosage' of each, and some kind of recipe that controls which qualities are used in what amounts for each different colour experience we are having. And some way to create these recipes for each specific spot in our visual field and transmit them to the relevant areas in our brains at sufficient speed for it all to work seamlessly and in real-time.<br>
<br>
Exactly how these five substances do their thing (and what that thing actually is) is presumably still a mystery, but at least we have some clarification of what Brent is talking about.<br>
<br>
So now that we've tidied up Brent's theory of colour vision (or at least expressed it in comprehensible terms, and laid out some necessary conditions for it to work), what about the varied and many other kinds of subjective experiences we can have?<br>
<br>
If Brent's theory is to have any legs at all, it must be extendable to all our experiences. I'm not sure how to do that, but it can wait for another thread, I think.<br>
