Creating and Editing Colors

To apply a color: Choose Line & Fill from the Type or Object menu, as appropriate. Click on the Line tab and select the line color from the Color pop-up menu. Click on the Fill tab and select the fill color from the Color pop-up menu. If you set the Type to Gradient, Radial or Shape, you will also have to select the color to blend to from the To pop-up menu.

To apply a lighter version of a color: Follow the above steps above, but change the percentage in the text box to the right of the Color pop-up menu to a value between 0 and 100%. 100% is the solid color and lesser values are lightened tints.

PageStream allows you to create new named and custom colors. Named colors are added to the Color pop-up menus and to the Color Palette so that you can use them again for other objects or text. Changing the color components of a named color changes all objects or text using that color. Custom colors are useful when you want to create a color for one instance and do not want it added to the pop-up menus and palette. Changing the color components of a custom color changes only the selected objects or text.

To create or edit a named color: Choose Define Colors from the Edit menu, or choose any color from the appropriate Color pop-up menu and click the Browse button to its right. The Define Colors dialog box will open. Click on Edit to edit the selected color. Click on New to create a new named color. If you click on New while a color name is selected, the default values will match that color.

To create or edit a custom color: Choose Custom from the appropriate Color pop-up menu. Click the Browse button to its right. The Edit Color dialog box will open. Set the color values and click OK.

NoteCustom colors are also created by the Blend feature in drawing programs such as Art Expression for intermediate objects.

SectionDefining colors
The Define Colors dialog box opens whenever you click the Browse button next to a Color pop-up menu with a named color selected, or when you click on a named color in the Color Palette while holding down an Shift key. You can also directly access to it via the Define submenu in the Edit menu.

This dialog box allows you to create new colors, edit any existing color, delete colors, append colors to the list, make a color list the default one, and save the color list to an external color file.

To edit an existing color: Select the color from the scrolling list and click Edit to display the Edit Color dialog box. Change the values and click OK.

To create a new color: Select the existing color closest in color to the new color and click the New button. This will open the Edit Color dialog box with the existing color's values set, but will not alter the existing color. Set the color values and give the color a name. Click OK to add the color to the list of colors.

To remove an existing color: Select the color from the scrolling list on click the Remove button.

To append colors to the existing one: Click the Append button and choose a color file or a PageStream document file from the File Selector. The colors contained in the color file or the PageStream document will be added to the current color list.

To make the existing color list the default color list: Click the Save button.

To save the existing color list to a separate file: Click the Save As button and type a name for the new color file.

NoteThe Color Palette also allows you to do these operations. Select Show Color Palette from the Window menu to display it.

SectionEditing colors
The Edit Color dialog box allows you to change the color values for a color.

To edit a color:
1. Set the color name for named colors.

Enter the color name into the Name text box. If editing a custom color this field will be uneditable.

2. Choose a color model from the Model pop-up menu.

Choose the color model which suits your needs best.

  • Gray: grayscales from 0 to 100%
  • CMYK: Cyan, Magenta, Yellow, Black
  • RGB: Red, Green, Blue
  • HSV: Hue, Saturation, Value
  • HLS: Hue, Lightness, Saturation
  • Crayons: 62 popular crayon colors
  • PANTONE Coated: PANTONE MATCHING SYSTEM
  • PANTONE Process: PANTONE Process Color System
  • PANTONE ProSim: PANTONE Process Simulated
  • PANTONE Uncoated: PANTONE MATCHING SYSTEM

NoteTo choose a PANTONE color, use a PANTONE Process Color Imaging Guide 1000.

3. Choose the type of color.

Click on Type to toggle between spot and process colors. For a process color, the color model and color values determine how the color will print. For a spot color, the color model and color values determine how the color will be displayed on screen, or printed if forced to a process plate.

4. Choose the print method.

Click on Print to toggle between Knockout and Overprint. Choose Overprint to make the objects to which this color is applied print on top of objects of other colors that are behind it. Choose Knockout to make objects of other colors that are behind it not print.

5. Set the tint value.

Enter a percentage between 0 and 100%; the smaller the value, the lighter the tint. This is designed to help you create consistent variations on a PANTONE color. You should name tints to reflect the base spot color. For example, a 30% tint of BrightRed could be named BrightRed30.

6. Set the color values.

Enter values into the text boxes for each color component, or adjust the scroll bars. For PANTONE or other library colors, choose a color from the list.

7. Click OK.

If you created or edited a named color, you will return to the Define Colors dialog box. Continue to create and edit colors if you want before clicking on OK in this dialog box.

SectionColor models
  • Grays: This is a simple color system for grayscales. Colors are defined as a percentage of black.
  • CMYK: This is the primary model used for printing and uses cyan, magenta, yellow and black intensities to create colors. It is a subtractive system: 100% of cyan, magenta and yellow create black, 0% creates white, equal percentages create gray, and varying percentages create different colors. Black is added to the three primary colors to produce contrast.
  • RGB: This is the primary model for video and uses red, green and blue intensities to create colors. It is an additive system: 100% of each color creates white, 0% creates black, equal percentages create gray, and varying percentages create different colors.
  • HSV: This model uses a color wheel to define colors and measures hue, saturation and value. Hue is the actual color and is specified in degrees because it is a point on the color wheel. Saturation is the amount of color relative to white, or the relative purity of the hue, and is expressed as a percentage. Bright colors are highly saturated while dull colors have low saturation. Value is the relative lightness or darkness of a hue. A color with a value of 0% is pure black.
  • HLS: This mode is similar to HSV but measures hue, lightness and saturation. Lightness is another way of measuring value.

SectionSpecifying a PANTONE color
It can be difficult to choose colors for printing that will print accurately on a printing press. There are many factors which affect color accuracy, including the press quality and the light in which you view the paper.

The PANTONE MATCHING SYSTEM was developed by Pantone, Inc., to standardize how spot colors are specified by commercial printers, ink makers and desktop publishing users. The PANTONE colors are standardized so you can be assured that the colors you choose will be printed accurately. Use the PANTONE Color Formula Guide 1000 for accurate PANTONE-identified solid color standards for coated and uncoated paper stock. Choose PANTONE Coated from the Model pop-up menu in the Edit Color dialog box to choose PANTONE MATCHING SYSTEM colors for coated paper, and PANTONE Uncoated for uncoated paper.

If you wish to use these PANTONE colors for process color separations, the PANTONE ProSim (Process Simulated) color model allows you to simulate many PANTONE spot colors using four color process separations.

The PANTONE Process Color System is designed to reproduce colors using PANTONE process inks. The more than 3000 colors are organized chromatically. Use the PANTONE Process Color System Guide for accurate PANTONE-identified color standards for coated paper stock.

For best results, you should work in 24 bit mode (millions of colors). With AmigaOS computers, this requires CyberGraphX and a graphics card. Always use a PANTONE Color Reference Manual to choose colors.

When you choose a PANTONE color for a named color, the PANTONE name will be inserted into the Name text box. The Type button will change to Spot or Process as applicable. It is recommended that you use the actual PANTONE name for spot colors unless you edit the color components by switching to another color model.

NotePANTONE Color Computer hard copy simulations used in this product are four-color process simulations and may not match PANTONE-identified solid color standards. Use PANTONE Color Reference Manuals for accurate color. PANTONE Color simulations are obtainable only on licensed hardware that is driven by qualified, Pantone-licensed software packages.
