Additionally, it is helpful to have a 100% pure black channel (black ink only) because we will be using that channel exclusively for our line art. CMYK is the color space that is used in the 4 Color printing process and the one that you should use if your work is ultimately going to be printed. In printing, as it is in illustration, you already start out with white (the surface of the paper, art board, a blank digital file). Albert Munsell authored two books on the subject: 'A Color Notation' (1905) and the 'Atlas of the Munsell Color System' (1915), and hue, tone and saturation are now commonly used everyday terms in color theory and color management.ДЇor the Additive Color (RGB) process to work, you need a light source (sun light, computer monitor, etc.).

Setting the color space for an image file is done through the Image>Mode setting, with a select of Bitmap (B&W), Index (256 or less, color GIF), Grayscale, RGB (3 color), CMYK (four color), Lab Color and Multichannel. In the Subtractive Color process, black is the combination of all colors. In the Subtractive Color (CMYK) process, when you combine Yellow, Cyan, and Magenta (CMY), the combination produces black. In the Additive Color process, white is the combination of all colors. Notice that when you combine Red, Green, and Blue in the Additive Color process, the combination produces white. Subtractive Color) is a better choice.ДЄdditive vs Subtractive Color: The diagram above illustrates the difference between Additive Color (RGB) Fig. Although there may be many good reasons to work in RGB (web graphics only, smaller file size, etc.), for our purposes, CMYK (A.K.A. If your work is going to be printed, you should be working exclusively in CMYK and not in RGB.
