I was recently playing around with the design of my twitter page and got it to look like Garland, the default design for Drupal. A number of you have asked me about it, so I thought I'd publish the values I'm using. So, if you want your Twitter page to also look like Garland, you can input the following values into your Twitter design.

Background Color:

EEF5FA

Background Image:

garlandtwitter.png

Text Color:

494949

Name Color:

494949

Link Color:

027AC6

Sidebar File Color:

E1F0FA

Sidebar Border Color:

E1F0FA

Of course, I'd recommend taking my website logo out of garlandtwitter.png, and putting your own image in there, but that's completely up to you.
