Color blindness

[geoff-h -at- MTL -dot- FERIC -dot- CA]

 The most common colorblindness is the inability to
 distinguish between red and green, and more men have this
 than women. The easiest way to determine whether someone
 will be able to perceive your color choices is to print a
 color copy, then photocopy it into black and white. If the
 difference is still visible, then it will probably be
 distinguishable even to color-blind viewers.

 Technojargon and details: Color differences rely in part on
 the "value" of each color ("value" represents how much
 black the color contains), and that's why the photocopy
 trick works so well. There are other types of
 colorblindness; for example, some viewers can't distinguish
 between colors even if they have different values, but
 they're a very small minority.

 As for why men can't dress themselves, I can't rely on
 colorblindness for my excuse... just on a professional job
 requirement (I'm an editor, mostly). In the words of Dave
 Barry: "Always remember, if editors were so damn smart,
 they'd know how to dress."
