Section 3.2: Color Contrast
When typing in text you want to consider the color contrast between the text and the background. For small text (under size 18), a good contrast ratio to aim for is 4.5:1 or higher. For bigger text (over size 18) a good contrast ratio is 3:1 or higher. Black text on a white background or 21:1 is considered to be the most accessible contrast ratio.

Backgrounds with crazy features or patterns should be avoided at all costs.
