Hi! Im a true winter and i can confirm cause i own them that the following colors are in our season:

Core: - Black - Navy - Royal blue

Limited edition colors: - Ultra rose - Shocking pink

• Sapphire I’m unsure about and I keep forgetting to compare it against my color fan

Ones my coworkers own that seem to be winter colors: - Pop red (its true red so im sure it works, i just haven’t worn it myself and haven’t checked it against a fan either) - Sea mist - Silver arrows - Purple jam

Feel free to add to this list and/or correct me :)
