On the UX side, the main goals are to
1. Understand the needs of the user
2. Understand psychological principles of perception and cognition.
3. Present the information in a way to enable the user to accomplish their task with the least cognitive load possible (typically.. there are edge cases where you want to introduce more friction but we will ignore those for now)
Start by getting a good understanding of the core Gestalt principles - https://careerfoundry.com/en/blog/ui-design/what-are-gestalt... - which influence how people perceive things. These principles are a core building block for UX and need to become an instinctive tool you use for arranging information and interfaces to achieve specific goals.
From there I'd suggest reading the following
- Don't Make Me Think by Steve Krug
- The Design of Everyday Things by Don Norman
- Everything by Edward Tufte, which as a data person you might have already read
Getting a foundation of understanding how people process their world will be crucial to growing a UX competency. The color and wording part will come after that foundation is built.
