Caution When Choosing Colored Envelopes for Ebay Standard Envelope

I bought a rainbow assortment of enveloped to use for standard envelope shipments.  It seemed like a percentage of my shipments were arriving with no tracking at all.  Think I finally figured it out.  The optical equipment in the USPS sorters gets confused by a red background.

If you're printing directly on the envelopes I can see how it could cause an issue. But if you're printing on a white label and affixing that to the envelopes I'd think the color of the envelope wouldn't matter.

That's exactly what I'm doing.  I'm cheap.
