I always used to see the letters of the alphabet as colors, an
eccentricity I mostly kept to myself thinking it was just a little too
weird for most people. Turns out I'm not alone: there's a new alphabet that's based solely on color,
which, if it catches on and doesn't become a 21st century Esperanto,
could influence the communication of our kids and eventually, their
kids.
Sure, there's probably not much we adults can conceive to
do with this other than say, "Cool! A rainbow that spells something!
Now what?" but our kids don't think like we do, at least not yet. Right
now, about all you can do is join the Kromofons
(that's the name of the alphabet but don't let that spoil your
experience) community and send one another Kmail, coded in color. Or
you can paint the outside of your house and send a message to your
entire neighborhood. But I'm sure your kids can think of things to do
with it that don't involve spray paint or tattoos.
