How do I change code completion UI colors?

I use custom dark look n feel (JTattoo HiFi) Seems like IntelliJ IDEA ignores the background properties, and so it looks like this:
Probably it requires some additional looknfeel property to set the background color fos this certain component.
If it's just property, then I could set it myself directly in the look and feel code.
Or can I just change it somewhere in the settings?
