Thanks for clarifying @MarcosAraujo.

We already support color tags on macOS. There is also an existing suggestion topic for adding color tags to iOS if you’d like to go upvote it:

Tag colors from macOS on iOS

Using colors in djay on macOS is so convenient. When transferring music from iTunes to the iPad, it’s great to see my HotCues, but it’s not great to see the colors of the songs I played in djay Pro on macOS not showing up. Djay is great… when will they implement that option?
