This limited range of QoR tubes is our list of favorite, unusual options they offer. The Payne's Grey and Neutral tint darken your color without drowning them in black. The irridescent colors are opaque and shimmer, adding a flair to your project. Try them for a smattering of stars or to add a that special touch of moonlight to your art.
From the manufacturer:
The unique formulation of QoR Watercolors accentuates the luminosity and brilliance of pigments even after drying. QoR provides the subtlety, transparency and flow of a great watercolor, with colors that have as much vibrancy and fire as the best acrylic or oil paint.
