7 Working with Colors The field displays all possible colors available if the current red value is kept and the other two values, green and blue, are varied. If the G button were selected, the field will display varying levels of red and blue; if the H button is selected, the field will display varying levels of saturation and brightness. Use the sliding scale to isolate the most important color characteristic and the field to vary the two remaining colors. The resulting possibilities should make it easy to isolate the desired color value. In the lower right-hand corner of the Color Selection dialog box, the Old color patch shows the current active color and the New color patch displays the color selection made in this dialog box. Note: When browsing for a color, it's helpful to click on the H button to see the rainbow of hues displayed in the sliding scale. Click on the desired hue, and choose a color from the field below the scale. Converting a Color Image into a Grayscale Image Occasionally, color images need to be converted into grayscale, black and white, images to make black and white print proofs, create an artistic effect, reduce file size, or make a duotone, etc. To convert a color image into a grayscale image: 1. Open the image (must be 24-bit). 2. Click Convert on the Main Menu, then choose To 8-bit Grayscale from the drop-down menu. Working with Colors 7-3
