Thank you all for your tips and advice.
I was able to change the background color by going in and adding some html to each block I wanted changed.
this is good enough for me.
here is an example what I added to the block:
<TABLE width="150">
<tr>
<TD style="width:100%; background-color:lightblue">
THEN ALL MY BLOCK CONTENT HERE
</TD>
</TR>
</TABLE>
