Currently, when multiple accounts are logged into the Android app, they are distinguished only by email address and a predefined color. Having multiple accounts yields in my case to random colors, three having the same color, one having another color.

Users cannot assign custom colors to specific accounts to make visual identification easier.

Please add an 'Account Color' setting in the Android app's account settings, similar to what is available on iOS (if it exists there) or web, allowing users to pick from a palette to distinguish their accounts.
