Polar Parlor
Five stops tuned to sit together without fighting — #006696 ink anchors the set, #9ed7ff opens it up, and #0091d3, #39aef1, #63bdf7 cross the middle in a analogous arrangement. Polar Parlor suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
