The Appeal of the PaletteOf all the electronic metaphors for traditional artisan tools, none is quite as elegant as the palette. Even if you dont know which end of the paintbrush to use, you surely have an image in your mind of the painter, brush in one hand, palette in the other. The palette has all of those pretty little dots, each a different color. Each painting might use its own palette with an entirely new set of colors. And so it is for CorelDRAW users, just not with the same tactile charm and allure. On the electronic side, a palette is a set of colors available for use on objects in a drawing. Typically, colors in a palette have a common bond, and that bond could be hues and shades (like a gray palette), type of usage (like a palette of eye or hair colors), or anticipated output (like a palette for Internet graphics). While the science of palettes runs deep, you might glean all you need to know if you keep in mind the image of a traditional palette. There is really only one other paradigm that you need to understand... The Concept of the Color ModelDRAW defines a color model as different from a color palette. While a palette has a fixed number of specific colors associated with it, a color model represents a formula used to produce colors. Usually millions of colors. The most obvious example is the CMYK color model, used for identifying colors in traditional color printing. An exhaustive range of colors exists by mixing the right percentages of the four colors cyan, magenta, yellow, and black. K is for black rather than B, so that its not confused with blue (which is actually not a primary color but a mixture of cyan and magenta). DRAWs default color palette, coreldrw.cpl, is based on the CMYK color model. Okay, lets say that again, because these are important distinctions. There is a palette called coreldrw.cpl (all palettes have .cpl extensions). It consists of exactly 100 colors, and they all have names, such as Navy Blue, Deep Purple, Pale Yellow, Dusty Rose, etc. The model on which this palette is based is the CMYK color model, which is capable of producing millions of individual colors. There are four reasons why coreldraw.cpl is used so extensively:
If painters need a color that is not on their palettes, they can reach for other paints or they can mix two colors from their palette to create a new color. In DRAW, the metaphors for those two actions are:
Remember, regardless of what palette is on screen, you can always go to the dialogs or the docker to mix or choose another color. And if you find a color that you want to use regularly, you can add it to your custom palette, using the Palette Editor shown in Figure 6.9. You can also assign your own name to a color. You can choose a technical name that describes the composition of the color, such as C13M12Y88; or one that is more descriptive of the colors use; or even, as in this case, one that reflects your opinion of it. Whatever name you choose will appear in the preview box on DRAWs status bar when you select an object that uses that color.
If you are producing color-separated work, you should work with a palette that uses the CMYK color model, or choose CMYK-derived colors from the dialogs or docker. If you use a different model, DRAW will convert your color choices to CMYK anyway when you make separations. Its anybodys guess whether the conversion will be to your liking, so its best to start with CMYK colors for your four-color printed work. The other color model that you might use regularly is the RGB color model for work that is destined to remain on screen. The obvious application today is the Web site, and indeed, the two palettes for creating Web graphics, the Netscape Navigator and Internet Explorer palettes, are based on the RGB color model. All light sources transmit colors as components of red, green, and blue, and computer monitors are certainly light sources.
Using Custom PalettesAlthough most users rarely change from the default coreldrw.cpl palette, the program ships with several other palettes. To use a different palette as your default, go to Window Ø Color Palette and choose one from the flyout menu. From that same menu, you can:
