Why isn't the yellow or green color available?

Colored postcard stock is only available on black and white 4.25" x 6", 4" x 9", 6" x 9" and 5" x 8" postcards.  If the colored stocks aren't available as paper color options in the job configurator, you may be using an incompatible product type or have opted for full color printing.

Colored paper availability has been spotty in 2022 and shortages are expected to continue into 2023. Periodic substitutions of one color instead of another are necessary at this time.
