Here is a comparison between NYX Cream Blush in Rose Petal and Natural.
In the pan, Rose Petal looks more brown than Natural but it seems like they have the same pink tone.

On my arm, Rose Petal is lighter than Natural. I like them both but prefer Rose Petal because on my cheeks Natural turns a brighter pink. Must be my skin's chemistry that reacts with the product.
