 {{#indexentry:pigments, solid color}}
 <p>The simplest type of pigment is a solid color. To specify a solid color you simply put a color specification inside a <code>pigment</code> statement. For example:</p>

 <p>A color specification consists of the optional keyword <code> color</code> followed by a color identifier or by a specification of the amount of red, green, blue, filtered and unfiltered transparency in the surface. See section <!--<linkto "Specifying Colors">Specifying Colors</linkto>--->[[Reference:Color Expressions|Specifying Colors]] for more details about colors. Any pattern modifiers used with a solid color are ignored because there is no pattern to modify.</p>
 {{#indexentry:pigments, color list}}
 <p>There are four color list patterns: <code>checker</code>, <code>hexagon</code>, <code>brick</code> and <code>object</code>. The result is a pattern of solid colors with distinct edges rather than a blending of colors as with color
 mapped patterns. Each of these patterns is covered in more detail in a later section. The syntax is:</p>

 <p>When developing POV-Ray scenes it is often useful to do low quality test runs that render faster. The <code>+Q</code> command line switch or <code>Quality</code> INI option can be used to turn off some time consuming color pattern and lighting calculations to speed things up. See <!--<linkto "Quality Settings">Quality Settings</linkto>--->[[Reference:Tracing Options#Quality Settings|Quality Settings]] for details. However all settings of <code>+Q5</code> or <code>Quality=5</code> or lower turns off pigment calculations and creates gray objects.</p>
 <p>By adding a <code>quick_color</code> to a pigment you tell POV-Ray what solid color to use for quick renders instead of a patterned pigment. For example:</p>

 <p>Each of the items in a pigment are optional but if they are present, they must be in the order shown. Any items after the <em> PIGMENT_IDENTIFIER</em> modify or override settings given in the identifier. If no identifier is specified then the items modify the pigment values in the current default texture. The <em>PIGMENT_TYPE</em> fall into roughly four categories. Each category is discussed the sub-sections which follow. The four categories are solid color and <code>[[Reference:Image Map|image_map]]</code> patterns which are specific to <code>pigment</code> statements or color list patterns, color mapped patterns which use POV-Ray's wide selection of general patterns. See [[Reference:Pattern|:Patterns|Patterns]] for details about specific patterns.</p>
-<p>The pattern type is optionally followed by one or more pigment modifiers. In addition to general pattern modifiers such as transformations, turbulence, and warp modifiers, pigments may also have a <em>COLOR_LIST</em>, <em>PIGMENT_LIST</em>, <code>[[Reference:Color Map|color_map]]</code>, <code>[[Reference:Pigment Map|pigment_map]]</code>, and <code>quick_color</code> which are specific to pigments. See <!--<linkto "Pattern Modifiers">Pattern Modifiers</linkto>--->[[Reference:Pattern#Pattern Modifiers|Pattern Modifiers]] for information on general modifiers. The pigment-specific modifiers are described in sub-sections which follow. Pigment modifiers of any kind apply only to the pigment and not to other parts of the texture. Modifiers must be specified last.</p>

 <p>A pigment statement is part of a <code>texture</code> specification. However it can be tedious to use a <code>texture</code> statement just to add a color to an object. Therefore you may attach a pigment directly to an object without explicitly specifying that it as part of a texture. For example instead of this:</p>
