Derwent Graphitint Pencils

When I reviewed Derwent's Graphitint pencils a little while ago, I asked Derwent about the pencils and the color range. They told me that people often ask why there aren't more yellows. Apparently this is because the black graphite mixed with yellow makes green, so its very difficult to make a yellow tone with them. So, when you need to use yellow, you might need to use a little regular colored pencil, applied last so as not to pick up much graphite. read my Graphitint Pencil review
