First question, so why not something simple? Mine is blue
Black! (Someone will have to show me how to highlight something in a certain color like the other posters)
Colour and other styles can be added with CSS.
Here's the code I used:
<span style=" color:#fff; background-color:#060; ">dark green</span>
For basic colours, you can use the name instead:
<span style=" color:white; background-color:black; ">black</span>
Which gives this: black
