Here's some technical details about the colors:

**Body** background-color: `#FFFFFF`, rgb: `255, 255, 255`

**Code/Blockquote** background-color: `#F5FDFF`, rgb: `245, 253, 255`

*It's nearly white!* Color-wise, I would classify it under gray not blue. I suggest increasing the **saturation** by about 8 units to `#E0F9FF`, rgb: `224, 249, 255`.

For comparison, the background color here on Meta.SU is `#EEEEEE`, rgb: `238, 238, 238`.
