This range cannot be fully relied on for lightfastness in the reds and yellows. 37 colours available. Sold as a set. Several colours are fugitive. Some colours not lightfast.
Pans are very convenient to use, extremely portable and are ideal for colour-sketching on location.
They can also be used very successfully in the studio for smaller works which don't require large rich washes. If using pans, moisten them with a water-mister before use and you'll save the life of your brushes. Some brands 'wet up' much more easily than others. The good thing about tubes is that they provide quantities of moist rich colour which is ideal for mixing big strong washes. They have their little pitfalls, such as drying out in very hot climates, having caps that stick or won't screw on properly.
