Color mode When you select Pixel Color in the Dropper dialog box, you can choose a color system in the pop-up menu. You can select RGB, CMYK, or Grayscale. The Color Dropper converts any color you click to the selected color system. For best performance, choose the color system that matches the col- ors you are sampling. For example, if you sample colors in complex RGB images with CMYK selected, slight delays can occur because Canvas must convert the image’s RGB values to CMYK values. However, you might want to select a color system that differs from an image. You might do this to see the effect of a color conversion, such as RGB to CMYK for printing, for example.
