Color study : a manual for teachers and students
Color study: a manual for teachers and students by Anson K. Cross, published in Boston by Ginn & Co. in 1896, aimed at schoolteachers and pupils learning color theory and its classroom teaching. The pictures are plain line diagrams of folded and cut paper shapes, with lettered points and labelled sections, showing how a square or triangle can be divided and folded into symmetrical forms that a designer might borrow for geometric pattern layouts.
