Changing the Color of an Image Object the Hue Saturation Function

Hue-Saturation is an extremely flexible tool. It can be used to completely change an image's color scheme, increase the saturation of one or more colors, create shades of gray by intensifying or decreasing color, or adjust the color of a selection. You can even use the Hue-Saturation slider to easily colorize old black-and-white photos or add color to new black-and-white photos to produce an artsy, nostalgic effect. In the following exercise, you'll use Hue-Saturation to dye your Easter eggs.

Activate the layer that you wish to modify. Choose Colors >Hue-Saturation. Click the Master button in the center of the color rectangles. You can move the Hue slider in the Adjust Selected Color control box to change the hue of the selected object. Moving the Saturation slider will either intensify the colors in the image or reduce them (until it becomes a grayscale image). To correct the image's (LAB) lightness, move the Lightness slider.

You have learned quite a bit about working with layers and masks. You know the most important color tools, and you can now create digital brushes, which allows you to produce new image objects, paint existing and new objects, insert text, and transform objects. And this is only the tip of the iceberg. Now you will learn how to select free forms using the Free Select tool as a polygon select tool. And you will get to know a tool that enables you to create arbitrary shapes. It's called the Paths tool. You can use it to cut an image object exactly at its contour or to create free, transformable shapes. The following section will define how the Free Select tool and the Paths tool work and what they are typically used for. You will also learn more about filters for light effects.
