You're both right. Marco, it's the low contrast of most broadcast
pictures that allow the eye to "average" the colors -- i.e., what the
guy above said. On the other hand -- I am sick and tired of seeing the
output of $10,000 studio character generators crawling across the
bottom of my screen. Anti-aliasing? They never heard the word! Nice
fonts? Uh uh, no way, Early Timex-Sinclair is the only font they do.

The keyword is "Contrast", Marco. The number of colors doesn't enter
into it.
