M Graham  This is a fine art gouache based on French formulas.  I have selected a 13-color spectrum palette of permanent lightfast colors including white.  The paints are a gum arabic base and are compatible with transparent watercolors. Honey i s added to the paint to keep it moist so the paint will not crack and crumble in the palette, and is also a deterrent to mold that the gum arabic binder of any water-based medium will attract.  Although I squeeze my paint out fresh with each painting session, the color could be placed in a palette and stored.  I use this paint with watercolor while traveling and painting on location. Most gouache brands are made for commercial art purposes as well as for the fine artist.
