Hi everyone, I am trying to add more hair colors to The Sims 2, I'm able to add new thumbnails, but when I click on the thumbnail it doesn't work. I tried to modify the "IGZWinBtn id" on the UI that I use. Some values work but these values are from old hair colors (black, brown, red, blonde) and if I use any of them, the old color button stop working.

*Update*
I added more two hair colors to sims 2, LightBrown and BrightRed. I really want to post, but this mod was originally made by greatcheesecakepersona, and i don't know If I have his consetment to post, here some cas image

I’m sorry I don’t have any information for you, but I’m very curious what you modified? I’m trying to figure out the UI myself and having no progress. What file is IGZWinBtn located in?

This UI is orignally made by greatcheesecakepersona, and the IGZWinBtn is located in cas-min-width-1920-additional-596px.package (this is just one of the files that modify the cas, the others have a different size

I just added a new color, copying and altering other colors swatch code. If you see the image, there is a new red color. I want to correct the thumbnails edges and make functional. The codes from original hair colors is
iid=IGZWinBtn id=0x00008800
