There are many bugs in the JavaFX 2.2 color picker, the quality of it was pretty awful.
The Java 8 color picker should work much better.
Try Java 8 and, if you still have issues that aren't tracked already, log bugs at: https://javafx-jira.kenai.com
Java 8 is available here:
You can also post some test code here (make sure it is complete and executable) and somebody can try to replicate your issues if you describe them well.
