HI-Approved Finger

Though we’ve tried very hard, a few issues linger
And we want everything to go well
Please only use an HI-approved finger

This flagship product, our new profit-bringer
That is, if it’s good enough to sell
Though we’ve tried very hard, a few issues linger

We market to both left- and right-wingers
So we can’t go too far, or we’ll end up in hell—
Please only use an HI-approved finger

We wanted to make an attractive ringer
But we ran out of funds for a real bell
Though we’ve tried very hard, a few issues linger

Chromacy

Asked for a form, got “color”. Replied, “Not a form!”. Asked someone else, got “villanelle”. So here is a villanelle about color.

A color between red and green.

Perhaps a color never seen?

For decades it has always been
Red, green, blue — that’s all
No color between red and green.

But what could one more receptor mean?
Would other colors start to pall
Against a color never seen?

Now think of vision no less keen
but in one way destined to crawl
No difference between red and green.

How does this fact…
