Cerulean and cobalt are both shades of blue.  Using each as a pool of letters, from cerulean we can get Lauren and from cobalt we can get Bacall

Consider these:

Lilac green                                                 Robin's egg blue

Using each color as your pool of letters, you can pull out the first and last names of a well-known couple.  Each color represents one of the pair. Who are they?
