You have not provided any details about how to repeat this issue.

Nonetheless, it is quite likely that your issue either is:

• You are not using a true-color terminal, refer here for details
• Or, you may be using a broken version of Vim; for example the default version of Vim on macOS does not correctly support termguicolors, use Homebrew instead (if this is your issue)

Please check the prerequisites, if you still have an issue then provide a repeatable test case.

Best of luck.
