Whispering Brook
Five stops tuned to sit together without fighting — #074bc0 ink anchors the set, #a7c7ff opens it up, and #3b79eb, #5e97ff, #79a9ff cross the middle in a tetradic arrangement. Whispering Brook suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
