Which light does the gel go on?

On the light you are pointing at. ADD TO THIS LIGHT on the REF card is the gel for the light in front of the camera, to make it read like the light you pinned.

Step by step

1. Pin the light everything should match: point at it and tap REF.
2. Point at the light you want to change.
3. Clip the gel from ADD TO THIS LIGHT onto that light, and read it again.

If that didn't work

To gel the other light instead, pin the second light and point at the first. A CTO answer warms the light in front of you and a CTB answer cools it.
