One possible reason why you are unable to see the calendar colours has to do with the settings on your computer.

To fix this:

1. Click on "Start", then "Control panel"
2. Double click on "Accessibility options"
3. Select the "Display" tab
4. Make sure that the "Use high contrast" box is not ticked.

Another possibility is that this is caused by a setting in Internet Explorer. If you're using Internet Explorer version 7, here is how to fix the issue:

1. Open an Internet Explorer session
2. Click on "Tools", then "Internet options"
3. On the "General" tab, under "Appearance", click on the "Accessibility" button and make sure none of the boxes are ticked.

If you are using a different browser or an earlier version of Internet Explorer, the menus may be slightly different. The good news is that prospective holidaymakers using the site will be able to see the colours on your calendar if their computers are set up normally.
