The way I understood it was the apple on a table test:

I was asked to close my eyes and think about an apple.

if you do it now, close your eyes for about 10 - 20 seconds and think very hard about an apple on a table.

then immediately after opening your eyes tell me what color the apple was.

For me and many others it is an absurd question. We only thought about the thing apple on the thing table, absolutely no visual representation.

For some of my siblings they saw the apple and could of course tell me the color and also the color of the table.
