What is the best way to color fondant?

Using gel colours. I add the colour to my fondant, then roll it into a snake and fold the ends in and repeat until all the colour is incorporated. Kneading and stretching it can over work the fondant. The method I use is gentler. It's also best to colour your fondant the night before so it has time to rest.

.......add the colour to my fondant, then roll it into a snake and fold the ends in and repeat until all the colour is incorporated. Kneading and stretching it can over work the fondant............

I agree with one slight difference.....once you have folded the ends in, twist it while pulling/rolling it and do that over & over until the color is mixed in well.
