Have you looked for ...
A medium that offers the best of both worlds: transparent
and easy to lift off like a watercolor, yet can be handled like an
acrylic
An acrylic paint yielding a matt and open surface
Vibrant glazes
Fresco-like finishes
Then try Aquacryl - the unique and highly exciting new medium.
These paints originally were sold at $8.50 each! This set includes 24
brand new, never used 30ml Lascaux Aquacryl watercolors.
