I haven't given up on finding a pair of reasonably priced Moe Light Honeycomb tangerine-gold pendants, but if I ever do, I think the Rejuvenation Corona pendant light would make a perfect modern light substitute. And while I'd personally go with orange, there are plenty of great modern color options available.
The Corona is based off of a truly mid-century pendant light, the EJS Lighting Fiesta (boy, that name sounds familiar).
From the Rejuvenation Corona page:
Ever heard of EJS Lighting Corporation? Neither had we.
Then we acquired a 1959 catalog from this Los Angeles manufacturer and realized that not only did they offer an astounding array of awesome mid-century modern lighting, but we had quite a few of their original fixtures hanging around in our product archives. The EJS line included hip hourglass chandeliers, classic pull-downs, elegant Swedish-glass shades, and the iconic "Glow-Bal" sphere pendants - but it was the Fiesta series that really caught our eye with its distinctive cylinder-in-a-cylinder design, mix-and-match color palette, and creative configuration options.
