Does this ever happen to the visual designers out there?

So I'm doing a presentation, and one of my graphics that I'm using everywhere is two concentric circles, one orange, one green. I haven't been able to get them to line up on the same center point.

It's been driving me NUTS - Keynote shows them aligned, they don't look right, they're always just a *little* bit off.

I fix it, I use it elsewhere, it's off.
I go back to the original, it's off.
I fix it, I come back to it, it's off.
I finally just chalked it up to a rendering bug.

I just figured it out.

It's chromatic aberration in my glasses - if I'm not looking at it dead center, it curves the two colors slightly differently, and the two circles are no longer on the same center point.

Physics is cool, though, isn't it?

Heh, yeah. It's rare that I run across two colors so intense right next to each other to trigger this. Neon signs do it all the time, but that's a known context. This one was facepalmy good.

Not just intensity, but also the fairly significant difference in wavelength--the closer the wavelengths, the less noticeable the CA.

Reducing CA is one of the reasons why good photographic lenses are so expensive. But you probably already know that.
