The Sennelier L'Aquarelle 12 half pan travel set is now one of my favorite on-the-go sets.  These are artist grade honey based French Watercolors.  They rewet very well and go on like butter.  Sennelier is known for their glazing capabilites and these excel in that arena.

My set contained Lemon Yellow (cool yellow) , French Vermilion (warm red/orange) , Alizarin Crimson (cool red) ,Carmine (cool red), diox purple, ultramarine deep (warm blue), phthalo blue (cool blue), Forest Green, Phthalo Green Light, Burnt Sienna, Payne's Grey, and warm Sepia.

There is room in the tin for 6 additional half pans if placed in the center.  In order to round out the palette to a full split primary, i plan to add a warm yellow, warm red, as well as phthalo green blue shade (PG7), a burnt or raw umber, and a magenta (PR122).  Lastly, a phthalo turquoise of PB16 which is one of my favorite mixing colors.
