White does make sense but I'm thinking going with a light beige for a contrasting look and can still see if it's not clean.

You can ask the person at the paint counter to put a few drops of some color into your paint. We use white exterior latex enamel for our greenhouse frames, dwc containers, and ask for 10-20 drops of royal blue. The guy at the paint counter at Lowe's really doesn't understand why we want this, says it won't show up (exactly !). Sure, 20 drops of any color in a gallon of paint doesn't sound like much.  It breaks up the white, just a bit.

We did the same thing with the garden picket fence, 20 drops of red. It looks white in bright morning daylight, and at dusk it is just a bit pink, but not much. Still clean, but a bit weathered.

That's a good suggestion. Good to know I'm not completely nuts about not using plain white.
