Support hex colors with underscore ( _ )

Example: 0xFF_FF_FF
It's in typescript, and when i remove the underscores, your plugin works fine.

It's not a common format, where do you see it in use?

Underscores are a part of a number. They are used for better readability, for example 1_000_000. In our project Lint forces hex colors to be with underscores, and the plugin doesn't recognize it.

Sorry, that's not a valid reason for me. I've never encountered such a rule and it doesn't justify development for a single use case. You're welcome to make a PR if you want though.
