Color Palette using custom Tailwind

after following this https://pinegrow.com/tutorials/customizing-a-tailwind-css-theme/
color palette looks empty. Is there anyway to fix this issue?

Ok these post were made in 2020/2021 it is now 2024 and this is still a problem that hasn’t been fixed? I only have the same colors in Tailwinds that is in that screenshot on this post. Has this been fixed or at a minimum have there been a workaround found?
