But you are still NOT hearing those frequencies.  You are probably noticing
beat notes between them and another frequency with is something entirely
different or possibly a subharmonic.

I think we have to detect something directly to notice it.

Maybe by the eye(-brain) system by smearing those pixels together but you
are not seeing those individual pixels.

I just think there's a limit that when you go beyond that limit, any more
pixels/area is just not going to make a darn bit of difference.

Some of the technology actually allows each spot to blend with its neighbor
which makes it look like it has more elements per unit area but can blur
hard borders.  Most people wouldn't notice.  Maybe because their eyes would
do it anyway...  Most of the printout technology has been in more saturated 
colors, less running on the paper and, yes, higher resolution.  Ooops, let's
not forget less fading.

Yeah, we haven't gotten a true blue pigment yet.  There is always some red
reflected (or transmitted) by blue pigments.  Also the "primary" colors
are different.  What's primary for one is secondary for the other.

I think you meant reflective color is what part of the illuminating light
that is not absorbed assuming that that color is in the orginal light 
(that's why tomatoes look so nice in the store and look pink at home, the
stores use fluorescent lights with boosted red in the produce section).

Does this sound like a blonde joke or what?  I always thought it was 
defective office furniture.  They sit down, a spring pops up about 
four inches and gives them a lobotomy.  :)
