I need to create a totally customizable react app, so i want the user to choose the color the aplication will use, then from code I need to edit bulma's framework classes to set the color the user wants to see in the app. I have been reading about sass, but i'm not sure.

  const [color, setColor] = useState("#b32aa9");//color must be saved in database
  return (
   <div className="App">
   <HexColorPicker color={color} onChange={setColor}/>
   <input type="text" value={color} readOnly/>  const [color, setColor] = useState("#b32aa9");
  return (
   <div className="App">
   <HexColorPicker color={color} onChange={setColor}/>
   <input type="text" value={color} readOnly/>
