You COLOR CORRECT the footage using the 3-way...and adjust things so that they match. HOW? Well, it's all done by eye. You adjust things until they match. You can start by making sure WHITE is the same on both..and then tweak the settings in the highlights, mids and blacks.
Again, HOW? This isn't something we can explain how via a forum. This is something people are trained to do for a living. So you can try to figure it out yourself, or hire a colorist.
