Do you have this [object] in a different color?

If you see something you like, but you do not like the color, you can ask if you can get it in a different color.

Another way to say this is “Does this come in a different color?” 

You can also add the name of the object after “this.”

I do not like this shade of red. Excuse me, do you have this in a different color? 

Does this bowl come in a different color? This will not match my kitchen.
