list of all available CSS colors (for the background)

I am writing some tiny javascript where in essence the content of a input
text value is used to set the backgroundColor of a div
div.style.backgroundColor = inputText.value;
The page might look like this:
Color: [black]
DIV
Because people might mispell the color I want to change it to a combobox.
The question is how do I know the list of all available colors ? e.g.
orange, cyan,blue,aqua are standard but blueaqua is not
