Text Size and Color
A good rule of thumb: Text should be three times the smallest size you can read from a normal viewing position — which, again, should be 20-30 inches from your monitor. When it comes to color combinations, your eyes prefer black text on a white background or other dark-on-light combinations. Avoid low contrast text/background color schemes.
