A pride-related song? At the start of Pride Month? What an absolute coincidence!
This song’s lights use boost colors for maximum effect. You can’t see them in BS Viewer, nor can you see them if you switch to an environment that doesn’t support them. Environments that support boost colors as of June 2021 include Linkin Park, BTS, Kaleidoscope, and Interscope.
Have a great Pride Month, and keep being yourself. 😀
