Using variables inside react native stylesheets wont recognize the variable

I import a color as props.color into my functional component and set it as the state ‘tagColor’. When I use tagColor as a value in my stylesheet to set the background color i receive the error ‘variable tagColor not found’

How can I use variables inside my stylesheet?

const Tag = (props) => {
  const [tagColor, setColor] = useState(props.color)

  return (
    <View style={styles.container}>
      <TouchableOpacity style={styles.tag} title='tag'>

const styles = StyleSheet.create({
  container: {
    alignItems: "center",
    justifyContent: "center",
    height: 25,
    display: 'flex'
  tag: {
    backgroundColor: tagColor,  

export default Tag;


Well, of course it doesn’t recognize tagColor, it’s in a different scope. Notice tagColor is in the scope of your function component, while the StyleSheet is a different scope.

One way to solve this is to directly pass the backgroundColor to the style prop, like that:

<TouchableOpacity style={{backgroundColor: tagColor}} title="tag">

Another way is to define the tag class in your StyleSheet as a function that receives the color and returns the style, like:

const styles = StyleSheet.create({
  container: {
  tag: tagColor => ({
    backgroundColor: tagColor,  

And then use it like that:

<TouchableOpacity style={styles.tag(tagColor)} title="tag">

I’d go with the first way if you don’t have any more styles other than backgroundColor. If you need more styles, go with the 2nd method.
