Feature Request: Placeholder Text Color

[wizebin]

Feature Request Description

Currently as a consumer of this library I have no way to control the placeholder color of the input field

Code

Something as simple as this would get the job done (sample from the fumi class)

       <Animated.Text
          style={[
            styles.label,
            {
              fontSize: focusedAnim.interpolate({
                inputRange: [0, 0.7, 0.71, 1],
                outputRange: [16, 16, 12, 12],
              }),
              color: focusedAnim.interpolate({
                inputRange: [0, 0.7],
                outputRange: [placeholderColor || '#696969', placeholderComposite || '#a3a3a3'],
              }),
            },
            labelStyle,
          ]}
        >

The new props could be something along the lines of the placeholderColor and placeholderComposite that I've added in this sample.

Reasoning

I would like to validate my user's input and indicate missing fields with a simple color change, currently I can add a different style like a border color, but a placeholder color would be slightly better.

Alternative

Having a custom placeholder component would fulfill this need

Nope, I'm crazy, missed the labelStyle prop- that suits my needs just fine!

I'm glad you figured it out @wizebin :)
