after repairing the permissions and restarting chrome the colors now displays correctly!
like the guy on stackoverflow I am also using an external monitor with a custom color profile. this seems to be the source of the issue. although the color looked fine in both safari and firefox all the time.
Seems to me that you have forgot to include the js-file of the carousel that you want to use. It should be included after jquery.js and before code you have put in galleryscript.js you need. I also suppose that the carousel comes with a CSS-file that you also have forgot to include.
