Typically there are 12 major colors in the Pantone seasonal color selection but this palette consists of only 10 plus a "Classic Color Palette" which includes 5 neutrals. One of the colors from this group is Sargasso Sea, a beautiful shade of Navy and still a popular neutral color that is considered to be "the other black". The added pearl in the clay recipe not only gives it the perfect shade but also adds a bit of shimmer and depth.
So here are the recipes for the Pantone Fall 2018 Fashion colors Sargasso Sea and Nebulas Blue using Kato clay:
8 parts Kato Blue
1 part Kato Black
1 part Kato Pearl
Same as recipe #9-3 Blueberry *
* Note: These clay color recipes are created using Kato Polyclay. Any of the base color "mixes" used are from my Clay Color System. (which is still on sale this week)
