What Makes Mars Red?

The sky on Mars doesn't look blue like it does on Earth. That's because Earth has this atmosphere which scatters the blue light down your eyeballs, but Mars doesn't. So then why is it red instead of like white from the sun? It's because of all of the dust, right? Mars doesn't have much atmosphere, but the dust is up there, and that dust tends to absorb blue light. And so when you look up in the sky during the daytime on Mars, you're seeing the red light reflected from that dust.
