You can personalize the logo and colors of your account by going to the Layout / Design section of your account settings:

1. At the bottom of your left side navigation click on Account Settings (if you don't see account settings, you aren't an administrator on your account. You will need to ask your system administrator to add you as an administrator ).
2. Click on the settings button under the Layout / Design section
3. Click on the "Upload your logo" button in the Account Logo section. Upload or enter a weblink to your logo
4. Once your logo appears, click on "Save Changes"
5. Once you've saved your logo, you will see new color options in the "Team Color" section (the system analyzes your logo to pull out colors - pretty cool!)
6. Select one of the colors or use the color picker to choose your color.
7. Click save in the Team Color section to save your selection.
