For the daring!
Wanna trick out your blog? Read on. Morgan asked how to change colors for text, background, etc. Here's how. Open up your template and look for the lines of html code that specify color (at the top of the template). They all have the word "color" in them so they're easy to find. You should be able to figure out which lines control the color for what. For example, here's a line that controls the color that links will appear in a blog:

a:link{color:#006400;text-decoration:underline;}Notice the giveaway here is the word "link" and "color." Dig? Yes, #006400 is the number of a web color. The whole palette of web colors with corresponding codes can be found here. Have fun! But remember to "Preview" before you "Save." If you don't like what you see then "Clear Edits."
