I always thought it would be fun if my colorino editorialized it's color
readings; "ghastly pale", "bilious green".

That's interesting.  (smile)   I have never tried color-testing myself.

Vince, are you actually chocolate-colored?  My color detector says I'm
orange, at least where I'm not brown or red.  I'm Caucasian, so I'd think
I'm more pink than orange. It always amuses me.

I've seen the color identifier you mentioned before, Andy.  I knew a guy
that had one and he used it to see if a page was blank.
It also would tell you the color spectrum, I believe.  Like, it would tell
you how much red and blue and the such were in the color.
The one thing I thought was weird about it was the bingo calling feature.
There was no way to review the winning numbers.
This same identifier said that I was vivid chocolate when I put it on my
skin.  I've never heard of vivid chocolate until then.
