Answer: Yes, research has shown that red mulch will result in higher early fruit yields on tomatoes. Something in the different wavelengths of light reflected off the red mulch is the reason for the difference in plant yields. Burpee carries a Reflective Red Mulch (see page 111 of the 1999 catalogue) in garden-size packaging.
