vocalists, what imagery do you like to use?

Question:

For trained singers/vocalists, what imagery do you like to use?

For people who are trained/experienced singers, what sort of imagery do you like to use, or have you found works best? I've been taking voice lessons for a little over a year now, and I've been trying to develop this more. In particular, I'd like to know what imagery you use to help you stay in key.

If you use colors, can that be learned or is it a natural talent kind-of-thing?
