high-contrast

I'm testing my company's established Swing application for accessibility issues. With high contrast mode enabled on my PC certain parts of this application are rendered properly (white-on-black) and some incorrectly (black-on-white).

The bits that are correct are the native components (JButton, JLabel and whatnot) and third party components from the likes of JIDE. The incorrect bits are custom components and renderers developed in-house without consideration for high-contrast mode.

Clearly it's possible to detect when high-contrast mode is enabled. How do I do this?
