I didn't expect the mod to be problematic as it is a rather simple mod. Let me know or you can add me if you need help modifying the colors. It seems to be working for me.

Probably, as much as I can say, you need to make sure you have UCP (Unofficial Code Patch) installed properly. The mod depends on it.

If you cannot make this work from workshop, you can always copy the contents of the mod
( D:\Program Files (x86)\Steam\steamapps\workshop\content\298050\3350366734 for me. You might need to change the directory depending on where you installed Steam)

into a new folder where you need to place that folder in C:\Users\<username>\Documents\Master of Orion\Mods (this is basically in your Documents folder. If there is no such directory for Mods you can create the folder yourself).

And if you want, you can also change the colors with any text editor with the hex values of new colors depending on whatever you prefer.

cannot get this working for the life of me after 3 days of trying lol
i wish CtS had just included color pickers like Battle At Antares.
