Here is a quick comparison of the L'Oreal Infallible Le Rouge lipstick in Ravishing Red (left) and Target Red (right). Frankly, I don't see the difference so I thought I would throw up the swatches to save ya'll $10.00.
If I was FORCED to share a difference between the two colors, I would say that the Target Red (right) is slightly deeper in tone. Truly the difference is almost perceivable to the naked eye. I would say go for one or the other, since the color is gorgeous, but don't bother with both.
