Answer 1

You might consider using a color theme

Since VSCode 1.44 (March 2020), you now have

Theme Support for Semantic Tokens

Color themes can now write rules to color semantic tokens reported by language extensions like TypeScript.

"semanticHighlighting": true,
"semanticTokenColors": {
    "variable.declaration.readonly:java": { "foreground": "#00ff00" "fontStyle": "bold" }
}

The rule above defines that all declarations of readonly variables in Java shoud be colored greed and bold

See the Semantic Highlighting Wiki Page for more information.
