Citrine draws upon the machine-driven typography of the first American PC boom of the 1980s: word processing typefaces made for easy reading at low resolution, and in-game typography. A large x-height means easy onscreen reading; a round joint means friendliness. Citrine is a typeface for writing, loosely based on the Epoca typeface (made for the Hermes 3000 typewriter). Citrine starts with Epoca’s essential widths and spaces, then adds tension with flat sides in curved forms, a double-barrel lowercase a and the tighter spacing necessary for modern screen reading. Citrine is five weights + true small caps for each, sized to the lowercase. You can set that as unicase, if you’re one of those people.
