identify a hue by placing your value viewer over your photo reference, then asking yourself these four questions:

what do you see? pink?

is it an orangish-pink or a purplish-pink?

is it bright or dull (lots of gray)?

is it a light pink or a dark pink?

Wwith the hue identified, begin with the lightest value color you see, applying lightly.

add layers by value, starting with the lightest and gradually increasing to darker values.
