Cobalt Blue

This is a sample of some Cobalt Blue mixed with black... and then some with white. From an oil painting called 'Dancing in the Living Room' by moi.

Also known as Leyden blue or Thenard's blue, it is a bright, clear blue pigment which is permanent in all techniques including fresco. Discovered by Baron Thenard in 1802, it was introduced to artists about 20 years later and became a standard color, replacing the unsatisfactory smalt. (Michael Clarke)
