Change colors of a map

I have a website ( http:// [login to view URL] / Z1HoTx ) with a world map but I do not like the color sheme. Please think about a nice color sheme (background color and country colors) and chanage the colors. You need to change the color codes in the javascript of the site. Please use a bright background. And take into account that countries in the same time zone need to have the same color. A few countries (Venezuela, Iran, Afghanistan, India, Myanmar and Central Australia) have color that are in between the colors of the time zones east and west of the country. Important is that the map looks good in the end.
