The periwinkle blue seems to have less vertical banding effect than 
the gray I normally use.  You can barely see it in the picture.  A 
little more so on the screen but still very faint.

The white on black 80 column text in the picture is more saturated 
than on the screen due to my camera having trouble getting it right. 
On the screen there is some variation of the 'whiteness' in parts of 
some letters.  Still easily readable though.
