Yes. You can even dial in the warmth of the white. Some of the preset patterns even work with white colors, so you can have white lights that twinkle. The bulbs are slightly frosted, so the colors combine quite well.
If you have them set up with Alexa, you can turn all of the presets white by just telling Alexa to turn the lights white. This works even for presets that don't have color options available on the app.
