the specification says they should:
http://www.w3.org/TR/REC-smil/#region

"The region element has the following attributes:

background-color 
      The use and definition of this attribute are identical to the 
      "background-color" property in the CSS2 specification,
      except that SMIL basic layout does not require support for 
      "system colors". 
      If the background-color attribute is absent, the background is 
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
      transparent. "
      ^^^^^^^^^^^^

let me know what you find in your experiments
