Suggestions on software UI design

The software works very well, The function of the software is very good, can design the language almost meaning, the playback interface is very monotonous, and in light mode, many color shades are the same, the human eye looks very harsh, poor readability. Some UI design is not very simple, an interface has multiple graphics and colors, making people visually tired. I admit it's a music-seeking software, but a more delicate and beautiful UI design or animation design allows users to unconsciously use frequently and stay for a long time, and visually comfortable design will make the software look more high-end and easy to use.
