LaTeX’s 0125 capabilities depend on the printer driver. However, the <samp>pdftex</samp>, 0126 <samp>xetex</samp>, and <samp>luatex</samp> printer drivers are today by far the 0127 most commonly used. The models below work for those drivers. All but 0128 one of these is also supported by essentially all other printer drivers 0129 used today. 0130 </p> 0131 <p>Note that color combination can be additive or subtractive. Additive 0132 mixes colors of light, so that for instance combining full intensities 0133 of red, green, and blue produces white. Subtractive mixes pigments, 0134 such as with inks, so that combining full intensity of cyan, magenta, 0135 and yellow makes black. 0136 </p> 0137 <dl compact="compact"> 0138 <dd><a name="color-models-cmyk"></a></dd> 0139 <dt><code>cmyk</code></dt> 0140 <dd><p>A comma-separated list with four real numbers between 0 and 1, 0141 inclusive. The first number is the intensity of cyan, the second is 0142 magenta, and the others are yellow and black. A number value of 0 means 0143 minimal intensity, while a 1 is for full intensity. This model is often 0144 used in color printing. It is a subtractive model. 0145 </p> 0146 <a name="color-models-gray"></a></dd> 0147 <dt><code>gray</code></dt> 0148 <dd><p>A single real number between 0 and 1, inclusive.

The first number is the intensity of the red component, the 0155 second is green, and the third the blue. A number value of 0 means that 0156 none of that component is added in, while a 1 means full intensity. 0157 This is an additive model. 0158 </p> 0159 <a name="color-models-RGB"></a></dd> 0160 <dt><code>RGB</code></dt> 0161 <dd><p>(<samp>pdftex</samp>, <samp>xetex</samp>, <samp>luatex</samp> drivers) A comma-separated 0162 list with three integers between 0 and 255, inclusive. This model is a 0163 convenience for using <code>rgb</code> since outside of LaTeX colors are 0164 often described in a red-green-blue model using numbers in this range. 0165 The values entered here are converted to the <code>rgb</code> model by 0166 dividing by 255. 0167 </p> 0168 <a name="color-models-named"></a></dd> 0169 <dt><code>named</code></dt> 0170 <dd><p>Colors are accessed by name, such as ‘<samp>PrussianBlue</samp>’.
