[Solved]-Change the background color of a screen with react native-Reactjs

try adding tintcolor to your navigation options

static navigationoptions = {
    title: navigation.state.params.title,
    header: navigation => ({
      titlestyle: {
        color: '#ffffff'
      },
      tintcolor: '#f5fcff'
    })
}

if you want to change the header color, then try this.

static navigationoptions = {
     title: navigation.state.params.title,
     headerstyle: {backgroundcolor:"red"}}

if you want to change the background color of the screen that is rendered then set

<view style={{backgroundcolor: 'red', flex:1}}> </view>
