Is there anyway to change placeholder color?

[Trịnh Văn Minh]

<CNRichTextEditor
placeholder={'Write your email here...'}
ref={input => { this.editor = input }}
style={styles.editor}
styleList={customStyles}
placeholderColor = {Colors.redCharm}
value={value}
onSelectedStyleChanged={onSelectedStyleChanged}
onSelectedTagChanged={onSelectedTagChanged}
onValueChanged={onValueChanged}
/>
