94 CHAPTER 4 Making Color and Tonal Corrections To colorize a grayscale image or create a monotone effect: 1 If you are colorizing a grayscale image, choose Image > Mode > RGB to convert the image to RGB. 2 Open the Hue/Saturation dialog box. 3 Select Colorize. The image is converted to the hue of the current foreground color, if the foreground color is not black or white. The lightness value of each pixel does not change. 4 Use the Hue slider to select a new color if desired. Use the Saturation and Lightness sliders to adjust the saturation and lightness of the pixels. 5 Click OK. Using the Remove Color command The Remove Color command converts the colors in the image to gray values. For example, it assigns equal red, green, and blue values to each pixel in an RGB image to make it appear grayscale. The lightness value of each pixel does not change. The Remove Color command can also be used on a selection only. This command has the same effect as setting Saturation to -100 in the Hue/Saturation dialog box. Note: If you are working with a multilayer image, Remove Color converts the selected layer only. To use the Remove Color command: Choose Enhance > Color > Remove Color. Using the Replace Color command The Replace Color command lets you create a mask around specific colors and then replace those colors in the image. You can set the hue, saturation, and lightness of the area identified by the mask. The mask is temporary. To use the Replace Color command: 1 Choose Enhance > Color > Replace Color. 2 Select a display option: • Selection to display the mask in the preview box. Masked areas are black and unmasked areas are white. Partially masked areas (areas covered with a semitransparent mask) appear as varying levels of gray according to their opacity. • Image to display the image in the preview box. This option is useful when you are working with a magnified image or have limited screen space. 3 Click in the image or in the preview box to select the areas exposed by the mask. Shift-click or use the eyedropper + button to add areas; Alt-click (Windows), Option-click (Mac OS), or use the eyedropper - button to remove areas. 4 Adjust the tolerance of the mask by dragging the Fuzziness slider or entering a value. This controls the degree to which related colors are included in the selection. 5 Drag the Hue, Saturation, and Lightness sliders (or enter values in the text boxes) to change the color of the selected areas. 6 Click OK.
