Increase entry text contrast
It would be nice if the entry text was a bit darker to increase contrast between the entry text and the entry background. The text color is appropriate when viewed on a white background, but it is a bit light against the grey.
I would suggest changing the entry text color to somewhere between #111 or #000, these maintain similar or greater contrast ratios as the current text to the white background.
For the pedantic (and because I looked it up), the current contrast ratio of 5:1 currently fails the W3C WCAG 2.0 level AAA requirement of 7:1, and barely passes the level AA requirement of 4.5:1.
