Weaver lets you set the colors of most parts of your web pages – backgrounds, titles, links, and more. Deciding on a set of colors that look good together is a big part of web design.
A web site called HTML-Color-Names.com is just the ticket. It starts with the named HTML colors (while using a color picker to get a hex value is common, there are color names, too.), and will display a page with several colors that go well with the name color. This is a great place to start when picking colors for your pages.
