The background colour alternates between white and very light blue when using the classic template. How can I get this to work with the gloss black template using 1.3.0.2

I looked up the stylesheet for classic and found this code:

TR.productListing-odd, TR.upcomingProducts-odd {
background: #ffffff;
}

TR.productListing-even, TR.upcomingProducts-even, .productsNotifications {
background: #eff4f8;
}

Can I simply paste this somewhere in the gloss black stylesheet?
