7 Working with Colors Changing the Active and Alternate Colors At the bottom of PhotoStudio's Tools Palette are two overlapping color swatches staggered one atop the other. The top swatch represents the active color while the bottom swatch represents the alternate color. The active color is the color that is applied to the image by the various brush and function tools. The alternate color serves as the background color and also makes a convenient "on deck" color because you can switch it to the active color simply by clicking its swatch. Note: If the mouse pointer is moved over the color swatches, the Status Bar will display their names and respective color values. To change the alternate color: 1. Click on the Alternate Swatch to make it the active color. 2. Select a color using one of the four methods described in the following paragraph. 3. Switch back to the original active color by clicking on the original active color Swatch. There are four ways to change the active color: 1. Use the Eyedropper Tool to match the active color to a color in the image. 2. Click on the Color Grid icon to select a color sample from the Color Grid. 3. Click on the Color Spectrum to select a color from the Color Spectrum. 4. Click on the Color Selection button to bring up the Color Selection dialog box. Use this method when using the HSV color model to select a color, or when other color selection methods are imprecise. Using the Color Selection Dialog Box The Color Selection dialog box provides many color selection options, including the RGB and HSV color models. By default, the Color Selection dialog box is in RGB color model with the red spectrum selected. This is indicated by the radio button next to the R color channel in the top right-hand corner of the dialog box. If you know the RGB values of the color you want to select, enter them into the R, G, and B value boxes, then click OK to make it the active color. To switch to the HSV color model, click the radio button next to the H, S, or V. If you know the HSV values of the color you want to select, enter them into the H, S, and V value boxes. The sliding scale at the top of the dialog box and the field below it provide a two-part system for in-depth color selection. The button that is checked indicates the color characteristic currently being examined. The scale always shows the range of possible values for that characteristic. For example, if the button next to R is selected, the slider will indicate a range from black, no red, to bright red. Clicking at different spots on the scale changes the amount of red in the current color selection and in the field. 7-2 Working with Colors
