Notes

For many journals, it is very expensive to have figures with colors in the printed version. But nowadays, the printed version of a paper is not very important because most people get numerical papers on the web. So a good solution for many figures is to use colors that can be differentiated in black and white. This function produces pdf files with color charts helping researchers to choose colors adapted to this requirement.
