Is white text on red background readability?

The perception by many people is that white-text-on-red is easier to read than dark-text-on-red.

Blue on grey is also apparently fine, but seems to many to offer poor visibility.

Is white text on blue background readability?

To ease the eyes, use colored backgrounds in blocks–for example, using a blue background with white boxes for text breaks up the design, provides the right level of contrast, and offers good readability. Avoid colors that are too light (like yellow), since they will not create enough contrast.
