In a bit of a hurry here and this is a real 'newbie' question!

I am currently getting set up to do all my own processing at home. I have an opportunity to buy an enlarger on ebay at a real knock down price. However I am not sure if it is a colour or bw enlarger. I am also not sure of the difference between a colour and a bw enlarger. So my question is this: As it is my intention to only produce black and white prints, can I use a colour enlarger to produce black and white prints?

Any answers within the next thirty minutes would be great! lol!

Thanks in advance!
