Is there a difference with the Cricut replacement blades? Why are they different colors?

Can I use the same blades on the expression that can be used on the baby one?

I've only seen the blue based blades sold.

According to their ad for the Expression model, they use the same blade:

"Now shipping, the Cricut Expression is the newest addition to the Cricut family of products. The new Cricut Expressions is a much larger unit, meant to stay on the table or in a media room. The good thing is that BOTH models use the same cartridge and the same blade housing and blade."
