Hello, how have you been?

prove is a different shade and is in the bottom left of the circle

You genuinely can't prove that you can see the difference, nor can you prove you can't.

a little microsoft paint might help

What if you went and made an outline, then filled the outline. I'm serious about this: nobody will 100% believe you, unless they give up or have good enough logic. Until there is a way to see exactly what another person sees, of course.

If you open the image in paint, then use the fill tool on the circle, it will not fill in the entire circle

It could have reached a pixel filling limit.

Again, you could have made an outline.

how about this, go try it for yourself

I don't know what you're getting me to try

open it in paint, use the fill tool and then click on the circle

Can’t see the difference, but I can read the sentence from the colors: prove can’t you it
