We used Show Stopper with Sealskin for this example. Sealskin is a very dark brown color. When we combined it with red, it appeared rather charcoal gray.
For this fun pattern we used the following colors: Sealskin (dark brown), Peacock Blue (teal), Anew Gray (light gray), Library Pewter (light brown). As you can see Sealskin appears to be much lighter and a bit more brown in this color combination.
