How It Reads#3D5773 set as type with the kit Chromary builds for it, both ways round, strongest first. Each is graded by APCA, the measure of how strongly text stands off its ground as eyes see it: Any text and Body text read at every size, Headlines and large text from about 24 pixels, Display sizes for names, logos and big headlines. Pairings too faint for text, or that collapse for red- or green-blind readers, are left out. The small numbers are the APCA score (Lc) and the WCAG 2 ratio, for anyone working to a standard.
