Open HelloColorPicker and enable the commented out line to turn on the caspian stylesheet. Note the many graphical glitches, including:

1) The divider line to the left of the arrow appears on hover - it should never show for the 'default' and 'hidden label' ColorPickers, and should be showing all the time for the 'SplitButton' ColorPicker.
2) There is not enough padding on the right in the 'Button' ColorPicker.
3) The ColorPicker popup looks really ugly - compared with the screenshot here: http://docs.oracle.com/javafx/2/ui_controls/color-picker.htm#BABHFGHA it appears that an extra black border has appeared.
