Different Colors for different sections?

Hi there,

I am developing a website for my local town which will list local businesses, events and jobs.

At present, I have my primary and secondary colors which I have used through out my homepage layout. I think this works ok, but I am now wondering if I should be breaking each of my main sections (local businesses, events and jobs) into different colors.

Is this a good idea or not? Or should I stick to the 2-3 colors and shades of these for each section? If I use too many colors I’m worries it will become messy.

Any thoughts and suggestions would be welcome. Thanks!
