Changing colours

I have searched bug cannot find an answer to this. Aeon nox running on win 7, frodo. Absolutely love the skin but all of a sudden the colour has been randomly changing from blue to green to purple and red amongst others. I haven't changed the theme or colours setting away from default as you will see in the pics but yet it changes every few seconds. It's very annoying and some of the colours make the fonts practically invisible. Every other skin displays fine and it is big a steering on my pc or my graphics card. Any ideas anyone?
