My favourite place to look for colours is http://0to255.com - it lets you get lighter and darker colours based on a certain colour, which is helpful for finding good 'hover' or gradient background colours. I also use https://color.adobe.com to find a good range of colours, and I stick to them to keep a consistent design palette across my wikis.
