Web Quality - Readability
Proper use of fonts and colors will make your website easier to
read.
Mind the Color Contrasts
Black text on a white background, or white text on a black background, is best for people with viewing disabilities,
and for display on bad equipment.
Grey text on a light background can give a very poor contrast:
| Grey text on a white background (#EEEEEE) |
| Grey text on a white background (#CCCCCC) |
| Grey text on a white background (#AAAAAA) |
| Grey text on a white background (#888888) |
| Grey text on a white background (#666666) |
| Grey text on a white background (#444444) |
| Grey text on a white background (#222222) |
| Grey text on a white background (#111111) |
Grey text on a dark background can also give a very poor contrast:
| Grey text on a black background (#222222) |
| Grey text on a black background (#444444) |
| Grey text on a black background (#666666) |
| Grey text on a black background (#888888) |
| Grey text on a black background (#AAAAAA) |
| Grey text on a black background (#CCCCCC) |
| Grey text on a black background (#DDDDDD) |
| Grey text on a black background (#EEEEEE) |
Some combinations - like black and red, black and blue, yellow and green -
always strain the eye:
| Black text on a red background |
| |
| Black text on a blue background |
| |
| Yellow text on a green background |
And some combinations are not so bad:
| Black text on a grey background |
| |
| Black text on a light blue |
| |
| Black text on antique white |
| |
| White text on dark blue |
