Hi Will. Thanks for the reply and congrats on rolling up all them points here on UNA.

I downloaded a fresh copy of UNA to compare the virgin files to my own. Under some circumstances, the icon color indeed becomes defined as dark via Base 64 code. What determines this icon color is still unknown to me.

You may be aware that hackers can use Base 64 images to hide their dirty tricks... So, it's kind of creepy.

I will update this thread when I know more. Hopefully, it will be days - not weeks or months.
