Yeah, you can open up the setting file and change the color. The color is based on the scope you assign to the highlight. By default it is “entity.name.class”, but you could change it to “keyword” or any other scope in your theme.
//Scope? (Defined in theme files.) ->
//Examples: (keyword/string/number)
"quote_scope" : "entity.name.class",
"curly_scope" : "entity.name.class",
"round_scope" : "entity.name.class",
"square_scope": "entity.name.class",
"angle_scope" : "entity.name.class",
"tag_scope" : "entity.name.class",
If you want more control of the color, you can add your own scope to your current theme file and tweak to any color you would like.

This would allow you to do this:
//Scope? (Defined in theme files.) ->
//Examples: (keyword/string/number)
"quote_scope" : "bracket.quote",
"curly_scope" : "bracket.curly",
"round_scope" : "bracket.round",
"square_scope": "bracket.square",
"angle_scope" : "bracket.angle",
"tag_scope" : "bracket.tag",
