react-native: multi color text view

You can do it better, my way:

CText = (props) => <Text style={{color: props.color}}>{props.children}</Text>

inside render add:

const CText = this.CText

and return

<Text>I am <CText color={'red'}>Blue color</CText> and <CText color={'blue'}>Blue color</CText></Text>

Simply nest <Text> elements

<Text>
    I am some text with 
    <Text style={{fontWeight: 'bold'}}>bold</Text> 
    stuff
<Text>

You can achieve this by using nested Text components

<Text style={{color: 'blue'}}>
    I am blue
    <Text style={{color: 'red'}}>
        i am red
    </Text>
    and i am blue again
</Text>
