First step is to take CORAL and put pen down where the darkest shaded areas would be - dependent on your lighting source. I chose a straight on light source for simplicity.
Then I take SUNKISSED PINK and colour over the coral and into the white area a little bit.
The next step is to take DUSKY PINK and take this lightly over the coloured area and into the white area again (use little circular movements to blend any stubborn areas).
Then take BLUSH and lightly blend in the white areas completely going over the image.
Now this next step can be slightly shocking but I like really pink cheeks so I use COCKTAIL PINK but you can use BABY PINK if you want lighter cheeks. Take the pink and colour in circles the cheeks then take dusky pink/blush and lightly blend the cheeks into the face.
And here is the finished skin tone that I adore to use (sorry for slightly blurry photo - hand was shaking).
Hope you find this tutorial useful xx
