probably true; otherwise, we'd expect computers to someday compute the
quale of ultraviolet and tell us what it's like.

because the heat radiated by a computer chip is not identical to the
chip itself; and, because the sensation of heat is not identical to the
molecular motion that indicates how hot the chip is.

neither have you established an identity claim.
do you want to give it a shot?
Hypothesis: that a color quale is identical to a physical object.
Fact: a physical object has a definite location that can be measured by
Prediction: a color quale has a definite location that can be measured
by scientific instruments.
Test of Hypothesis: induce an afterimage of the color complement type.
stare at a brightly lit green object for a while, then look away at a
white surface. you should see a reddish afterimage.
where is the red?
