Try out these two mental exercises:

Look at a clear blue sky and try to imagine the color red at the same time. Can you do it?

Okay.

Now, look at a blue sky and try to imagine the color *blue* at the same time. Yes, the same color. Can you do it?

It the latter case, do you stop seeing blue the moment you starting imagining it, and starting seeing blue the moment you stop imagining it?

I've heard someone claim this. What does your introspection say?

Debating whether the claim advanced in the first post--concerning the impossibility of (a) imagining an object to be one colour and (b) seeing it simultaneously as that colour--is true.

Is your only discursive ambition to engage in pointless and protracted argy-bargy over political issues? What a fulfilling life you lead!

I tried it. When I looked at the blue sky while imagining red, I saw a blue sky and imagined red simultaneously. When I looked at the blue sky and imagined blue, I saw the blue sky and imagined blue. I found that I could imagine shades of blue against the sky blue too. For some reason it was easier to imagine a darker blue than a lighter one. Whatever was supposed to happen I don't think it happened, but it was nice to take a break and look at the sky.

Is this some variation on the Stroop effect where if you color words with colors opposite to the color you call them you will trick someone into calling out the color of the word rather than being able to call out the color described by the word.

As a social corrolary to your visual treat, is it possible to imagine a negatively held view as incorrect when observing a news item that tends to confirm the suspicion of that stereotypical view?

Get a pair of binoculars and look at the sun through it. Try to imagine afterwards being able to see.

Warning to the intellectually impaired (otherwise you will also be optically impaired): DO NOT REALLY DO THIS!
