Fixes the default strings of preference colors
Fixes the default strings of preference colors

When a user clicked a button to show colorpicker where
the prefenrece for the color did not have a value,
colorpicker did not show the 'current color'.

The colorpicker script does not take 'rgb(...)' but it takes
hex rgb value.

Then this changes the format of default colors.
