How to add additional styles to existing Language?

[pulsar-de]

Hi@all, i’am using the syntax highlighting feature for the lua language and i have written some libs with custom functions. In this case i have tried to add a new style “utils” to get an own colormanagement for these functions but all trials fails. I don’t want to add these special functions to an existing style because i need a different colormanagement.

How can i add an additional style to my existing lua language?
