Stone Grove
Five stops tuned to sit together without fighting — #007178 ink anchors the set, #85e7ef opens it up, and #009fa9, #3cbcc6, #67c9d1 cross the middle in a monochromatic arrangement. Stone Grove suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
