I have switched to the Tri-Art Acrylic paints and love the results. The prices are good, colors are vibrant and so easy to work with, as are all of the mediums. I highly recommend this company and their products.
Tri-Art Artist Brushes - Long Handle Soft Synthetic - Angle
Rich pigment in a liquid; not a watered down version. Beautiful colour ranging from a luminous green to a deep ocean depending on thickness.
This is my favourite blue for creating warmth in the sky, and for mixing tints of turquoise.
