The term 'palette choices' refers to the range of colors available for an artist to use in their work. Two common palette choices are oils and HUES. Oils are a type of paint made from pigments suspended in a drying oil, such as linseed or safflower oil. HUES are colors that have been mixed with white, black, or gray to create a softer, more muted tone. Both oils and HUES can be used to create a variety of effects in artwork.
