I’m following this tutorial, but even after adding coolGray and shades here, they are not reflected on the frontend. [https://youtu.be/k-OZw8EzmMo?si=hwwMQJ\_gWTeYTfxH&t=713](https://youtu.be/k-OZw8EzmMo?si=hwwMQJ_gWTeYTfxH&t=713) ![bug.PNG](https://canada1.discourse-cdn.com/flex036/uploads/pinegrow/original/2X/5/501e4e48b27526c175af2b4a6cdcc0921406ae68.jpeg) I’ve tried saving and exporting the theme several times, but they are not reflected. I cannot find any description related to coolGray in the generated tailwind\_theme/tailwind.css. Is this a bug? ---
