The Color Test Book is intended for anyone, professional artist or otherwise to keep a record of the colors of markers, pens, pencils and other art supplies they use. Inside, you will find blank shape templates that offer you the chance to try out each color and record the cap or barrel number of the tool you are using, as well as a section in the back to keep notes about your supplies and a reorder list. This simple book will allow you to keep track of what color the ink is, as much of the time the color indicator on the pen is not a true match for the color of the ink. You will never have to guess again about which shade a color is and if it is what you are looking for. Great for those who love to collect adult coloring books or for professional artists that need a visual aide to assist them when choosing colors to with.
