Good design is readable design. Without a clear message, displayed in an easy-to-digest way, it’s easy to lose the meaning of any piece of design work. That’s why it’s so crucial that any design must be easy to read.
Designing for readability is a lesson in typography, but also in contrast. Contrast is the key to enhancing readability, and helping create a flow through the text in a logical manner so that users understand exactly what you want to say.
