Oyster Foundry
Five stops tuned to sit together without fighting — #006a69 ink anchors the set, #81dfdd opens it up, and #009897, #3ab4b3, #64c2c0 cross the middle in a complementary arrangement. Oyster Foundry suits restaurant branding that works on signage and receipts alike. The darkest and lightest stops clear AA for large text.
