For your argument about aliens to work here, I think you would be forced
to say that these aliens with brains wired differently from ours might not
only see 'green' as 'red' but also see '5' as '3'. In that case I would
say you are not referring to platonic ideas. If 5 exists objectively in a
platonic sense then it is perceivable by all intelligent beings in the
universe. In fact the SETI project works more or less on this assumption.
If green exists platonically like a number then, like the number '5',
green should also be perceivable by all intelligent beings, or at least by
all intelligent beings with suitable sense organs. The existence of a
being incapable of seeing green would not disprove the objective greenness
of green objects, any more than would the existence of a color-blind
person disprove the objective redness of tomatoes.

And Plato's world of abstract forms is in principle real and objective for
all beings. Intelligent beings *discover* the Forms.

And Plato's forms are primary, analogous I think to Locke's primary
qualities.
One interesting (and some might say philosophically fatal) consequence of
my relating Locke's primary qualities to Plato's primary forms is that
objects will have in theory an indefinite or perhaps even infinite number
of real objective qualia properties. A baseball looks white to you and me,
and really is white in an objective sense, but will look much different to
a blind bat perceiving it through sonar. That sonar quale must
nevertheless be understood as an objective quality of baseballs.
Presumably that sonar quale of baseballs exists platonically alongside the
'white' and 'sphere' ideas that humans access.

It seems then that you want to say 'proto-qualia' exist objectively in
objects, but not qualia.

But, again, Plato's forms are thought to exist objectively. If objects
exist objectively along with their Lockean primary qualities and objective
platonic qualities, and if qualia are objective, then I see no need for a
subjective component in the definition of 'qualia'.
I wonder if you really mean that qualia are something like Aristotle's
universals. This might be consistent with what you wrote earlier about
your subscribing to a 'weaker form of platonism' in which forms do not
exist separate from their instances. I think you mentioned set theory --
that qualia are like sets -- also consistent with Aristotle. Sets are
formed in a mind, whereas platonic forms exist before they are
comprehended.
