Reaction Roles
Let members self-assign roles with buttons or reactions. Design it here, then post it to a channel.
Colour roles (one-click setup)
Instantly create a set of pretty colour roles and a pick-one menu. Each colour gets its own row showing the role in that colour, so members can see how it will look before choosing. Everything is prefilled, rename the colours or tweak the message, then create.
This creates real roles in your server and posts a pick-one menu. The bot needs Manage Roles and its role near the top.
