The pencils that I used for this course are Prismacolor premier pencils. The colours that I used for the penguins were indigo blue, dark umber, canary yellow, violet, white. And you will need a colourless blender. Some other useful colours for your set would be lemon yellow, scarlet lake, crimson lake, cerulean blue and sienna brown. With all of those colours you can mix almost any colour that you need.
