Here's some code with various color combos.
Code:
<table width="600" border="1" cellpadding="0" cellspacing="0" bordercolor="#000000" bgcolor="#FF0000">
<tr>
<td bgcolor="#FFFFFF">1</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td bgcolor="#FFFF00">4</td>
</tr>
<tr bgcolor="#0000FF">
<td>5</td>
<td>6</td>
</tr>
</table>
Table is red background (600 wide with 1px black border)
Cell 1 is white
cell 2 is default table
cell 3 is default table
cell 4 is yellow
row 3 is blue
You have a css class="forms". Look for the color code #E4F8FA in there too.
