I usually include the following in my CSS to control the background color of the TinyMCE editor... in case I've set some dark background or image elsewhere in the design that causes trouble. You could certainly expand on this to meet your needs.
Code:.mceContentBody,
.mceEditorIframe {
/* TinyMCE Editor */
background-color:#FFFFFF;
}
.mceContentbody a,
.mceEditorIframe a {
color: #00F;
text-decoration: underline;
}
Just be sure to tell TinyMCE to use the stylesheet that contains this information. This is done by going to the Developer section of umbraco, expanding the Data Type treeview item, and selecting the Richtext Editor datatype. You'll see various options, including a list of your css stylesheets. Select the one(s) you need.
