LayOut contains five color pickers used to select color.Color Wheel Picker
The Color Wheel picker allows you to select a color by Hue, Saturation, and Brightness.
Select the color you want by clicking your mouse over that color in the Color Wheel picker. You can also click and drag the cursor around the Color Wheel to quickly browse through many different colors. You will see a dynamic preview of the selected color in the active color well at the top of the Color Picker.
The Color Wheel picker arranges color hue radially around the wheel, with the highest saturation at the outer edge of the wheel. Slide the value slider, to the right of the wheel, up or down, to change the brightness of the color.
The Color Wheel picker is the simplest and most versatile of the standard Apple color pickers, though it is also the least precise. You might want to use the Color Wheel picker to make a rough color choice, and then use one of the color slider pickers to fine tune your choice. Use the HSB color picker to fine tune or mix desaturated colors.Color Slider Picker
The Color Slider picker contains four pickers: Gray Scale Slider, RGB Sliders, CMYK Sliders, and HSB Sliders. These color pickers differ only in the components they use to mix colors. Select the Color Slider picker from the pop-up menu at the top of the picker control area to choose one of the color slider pickers.
Gray Scale Slider
Use the Gray Scale slider to select colors from the grayscale color range (shades of gray).
Adjust the slider until you see the color you want in the active color well. Alternatively, you can select a color by typing a percent gray value directly in the text box to the right of the slider. Or, choose from one of the five preset gray values below the slider.
RGB (Red, Green & Blue) Sliders
Use the RGB sliders to select colors from the RGB (Red, Green and Blue) color range. RGB colors are traditionally used when modeling color on a computer screen.
Drag the sliders left and right for each of the component colors (red, green and blue) to create the color that you want to use. The background color of each slider changes as you modify values to help you predict how adjustments will change your color mix.
Alternatively, you can type in exact numerical values for red, green or blue in the value boxes to the right of the sliders to precisely match a color that you have specified elsewhere.
CMYK (Cyan, Magenta, Yellow & Black) Sliders
Use the CMYK sliders to select colors from the CMYK (Cyan, Magenta, Yellow and Black) color range. CMYK is traditionally used to select colors intended for professional printing, where colors are usually specified in percentages of these four basic ink colors. RGB or HSB color pickers are generally sufficient for most work in LayOut.
Drag the sliders left and right for each of the component colors (cyan, magenta, yellow and black) until you have the color you want to use. To help you find an exact color , the background color of each slider will change as you modify values to help you predict how adjustments will change your color mix.
HSB (Hue, Saturation, and Brightness) Sliders
Use the HSB color sliders to pick colors from the HSB (Hue, Saturation, and Brightness) color range. HSB often gives you a more intuitive color model for selecting desaturated colors.
Adjust the sliders for hue, saturation and brightness until you see the color you want in the active color well.
Sometimes it is easier to mix de-saturated colors using the HSB color picker in conjunction with one of the other color pickers. Switch to another color picker to make your rough color selection, then switch back to the HSB color picker to fine tune or mix desaturated colors.Color Palettes Picker
The Color Palettes picker allows you to select colors from several predefined color palettes.
Use the List menu to select a color palette, create a new color palette, open an existing palette, rename a color palette, or remove a palette.
Use the Color drop-down list to create a new color, rename an existing color, or remove a color from the current palette.
Type the name of a color in the search box to find a color in all color palettes. You must click on the different palettes in the List menu to see if that color exists in a palette.
The Image Palettes picker allows you to load an image file into the color picker and select colors from anywhere in that image. The Image Palettes picker has a spectrum image loaded as a default.Crayons Picker
The Crayons picker displays a graphic redocument of a box of crayons with a small range of standard Apple colors. The Crayon picker is the simplest picker to use and is fairly limited in the range of colors available.
Click on the crayon whose color you want to use to select a color with the Crayon picker. The crayon's color will be transferred to the active color well.
