yes, that's what i've done already to get a reference on how to change it. i've open your PNG files to see the emblems you changed.the problem is I can't figure out how you saved them to the mod. are you suppose to open the PNG files of each i.e 24, 256, 64, banner, in a certain program to then be able to edit it an save it to to the mod? basically i'm saying how did you open the UI emblem file, recolor it and then save it back to the mod. I thought maybe PAINT would work but couldn't figure out how to save it after recoloring.

If u r using PFM - try to open my mod, and look what i've done
ui >> flags >> athens (or "faction_group_athenai")

how were you able to edit the UI files with the new emblems and save them to the mod? i've been using PFM and i've successfully edited all the files like uniforms, banners etc. but in the UI-Flags-Athens-Mon Files location, i can't figure out how to edit the png files and save the new emblem to the mod. Can you help?
