Hey fam,
How do i make the colour of a rectangle change based on the username/email of a user. I want to have a different colors for different users.
I know I can input color dynamically to the colour component, But am wondering where to get the hex code from?
Or is it possible to generate color from a rand function in adalo? if yes, how do I do so?

You can make a collection of colors with relationships to users, in the collection of colors an image (color photo) and a text where the color code is… you tell the user: select the color you want, update the current one there user in my color: and the color code is stored there… then in a rectangle you can put user\>mycolor

Hi Paul,
Addition to Santiago’s great reply!
I found a free API that you can get a random hex colour code!
