How to fill space between curves

The image below shows some curves I drew with the pen tool. How would I go about filling in the space in between each curve with a different colour?

Here is an example of what I need:

All help is appreciated.

Thanks,

Hi Dan,

So how did you make the example?

Hello DanTechGuy,

Select the lines, group them, "Ctrl + J".

Select the upper group, ungroup it, "Expand Stroke", do a Boolean operation "Add", then "Divide".
