That being said, some of the tribe colors interact oddly with some skins, such as ship windows of Elyrion not being changed to the applicable color.
In addition, there effectively is a way. The Hybrid Tribes are currently essentially broken. Rather than using the units for the first tribe, it only uses the color and city. For skins specifically, it only uses the color, which makes it entirely a pallette swap rather than an actual hybrid tribe, which is sort of odd considering that cymanti has sprites for all skin units which you can see with the Shaman. Any chance of fixing that?
That's exactly what we wanted the merged tribes to be - a cosmetic palette swap long before the addition of tribe skins. So, working as intended.
