You can upload your logo and change your organisation's account colors in the layout and design section:

To upload a logo:

1. Click on the "Choose an image" button
2. Select your logo from your computer, URL, or from other sources
3. Crop the photo to your desired size
4. Click "Save".
5. Select your desired size (small, medium, large)
6. Click "save changes"

Once you have saved your logo, the system will recommend a new primary color based on your logo. You can click on one of the shaded colors recommended, or use the color picker to the left. Once you've chosen your color, click on Save Changes.

NOTE: The "Save Changes" button only saves the information in the respective section. For example, you cannot upload a logo and select colors at the same time.
