Linework illustrations with flat colour added to the image either all over disregarding any three dimensional light changes there may be or picking out the major changes to give a hint of shape and form.
This is also a relatively simple process and the versions in the monochrome and grey scales section previously can be derived from these colour versions here so the costs are pretty much the same for both.
