River Foundry
Five stops tuned to sit together without fighting — #004e6e ink anchors the set, #73bfe8 opens it up, and #0078a6, #3293c3, #56a2cb cross the middle in a triadic arrangement. River Foundry suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
