Editor Before	Editor After

<style type="text/css">
.RadEWrapper *,.ContentElement * { color:#000000; }
.RadEContent, .RadEContentBordered, .RadETextArea { background-color:#222222 !important; color:#dddddd !important; font-size:12pt !important; }
.RadEContent a:link, .RadEContentBordered a:link {color: #ffcc00 !important; text-decoration: none;}
.RadEContent a:hover, .RadEContentBordered a:hover {color: #ffffff !important; text-decoration: underline;}
.RadEContent a:visited, .RadEContentBordered a:visited {color: #8000ff; text-decoration: none;}
.RadEContent a:active, .RadEContentBordered a:active {color: #ff8000; text-decoration: none;}
</style>

• The top line makes sure that the Style, Font Name and Font Size boxes don't have white text on a white background. So keep this color dark, the default here is black. I tried changing the color of the toolbars, but it'll take a lot more messing around with CSS to get it perfect. So the toolbar should stay white with a dark color text.
  
  .RadEWrapper *,.ContentElement * { color:#000000; }
  
  
• The second line modifies the background color of the editor. Adjust it to match your site. The default colors are very dark grey (#222222) with an almost white (#dddddd) text. You can also modify the font size (12pt) here because most of the time I'm squinting to see what I've typed. Make sure you keep the !important after each variable or it won't work
  
  .RadEContent, .RadEContentBordered, .RadETextArea { background-color:#222222 !important; color:#dddddd !important; font-size:12pt !important; }
  
  
• The last four lines modify the link colors inside your editor. I only added the !important to the first two, but you can include the last two if you're having trouble seeing the links. I left in the "text-decoration" but it really doesn't do anything unless you are in "preview" mode. You could also add an !important after these parameters, but then you'd have to add it to all four.
