-.SH DESCRIPTION
-The

-function returns the current RGB value for the pixel in the
-.ZN XColor
-structure and sets the
-.ZN DoRed ,
-.ZN DoGreen ,
-and
-.ZN DoBlue
-flags.
-The
-.ZN XQueryColors
-function returns the RGB value for each pixel in each
-.ZN XColor
-structure and sets the
-.ZN DoRed ,
-.ZN DoGreen ,
-and
-.ZN DoBlue
-flags in each structure.
-
-.LP
-.ZN XQueryColor
-and
-.ZN XQueryColors
-can generate
-.ZN BadColor
-and
-.ZN BadValue
-errors.
-.LP
-The
-.ZN XLookupColor
-function looks up the string name of a color with respect to the screen
-associated with the specified colormap.
-It returns both the exact color values and
-the closest values provided by the screen
-with respect to the visual type of the specified colormap.
-If the color name is not in the Host Portable Character Encoding,
-the result is implementation-dependent.
-Use of uppercase or lowercase does not matter.
-.ZN XLookupColor
-returns nonzero if the name is resolved;
-otherwise, it returns zero.

-.SH "COLOR NAMES"
-An RGB Device specification is identified by
-the prefix ``rgb:'' and conforms to the following syntax:
-.LP
-.\" Start marker code here
-.Ds 0
-rgb:\fI<red>/<green>/<blue>\fP
-
- \fI<red>\fP, \fI<green>\fP, \fI<blue>\fP := \fIh\fP | \fIhh\fP | \fIhhh\fP | \fIhhhh\fP
- \fIh\fP := single hexadecimal digits (case insignificant)
-.De
-.\" End marker code here
-.LP
-Note that \fIh\fP indicates the value scaled in 4 bits,
-\fIhh\fP the value scaled in 8 bits,
-\fIhhh\fP the value scaled in 12 bits,
-and \fIhhhh\fP the value scaled in 16 bits, respectively.
-.LP
-For backward compatibility, an older syntax for RGB Device is
-supported, but its continued use is not encouraged.
-The syntax is an initial sharp sign character followed by
-a numeric specification, in one of the following formats:
-.LP
-.TS
-l l.
-\&#RGB (4 bits each)
-\&#RRGGBB (8 bits each)
-\&#RRRGGGBBB (12 bits each)
-\&#RRRRGGGGBBBB (16 bits each)
-.TE
-.LP
-The R, G, and B represent single hexadecimal digits.
-When fewer than 16 bits each are specified,
-they represent the most significant bits of the value
-(unlike the ``rgb:'' syntax, in which values are scaled).
-For example, the string ``#3a7'' is the same as ``#3000a0007000''.
-.LP
-An RGB intensity specification is identified
-by the prefix ``rgbi:'' and conforms to the following syntax:
-.LP
-.\" Start marker code here
-.Ds 0
-rgbi:\fI<red>/<green>/<blue>\fP
-.De
-.\" End marker code here
-.LP
-Note that red, green, and blue are floating-point values
-between 0.0 and 1.0, inclusive.
-The input format for these values is an optional sign,
-a string of numbers possibly containing a decimal point,
-and an optional exponent field containing an E or e
-followed by a possibly signed integer string.
-.LP
-The standard device-independent string specifications have
-the following syntax:
-.LP
-.\" Start marker code here
-.Ds 0
-CIEXYZ:\fI<X>/<Y>/<Z>\fP
-CIEuvY:\fI<u>/<v>/<Y>\fP
-CIExyY:\fI<x>/<y>/<Y>\fP
-CIELab:\fI<L>/<a>/<b>\fP
-CIELuv:\fI<L>/<u>/<v>\fP
-TekHVC:\fI<H>/<V>/<C>\fP
-.De
-.\" End marker code here
-.LP
-All of the values (C, H, V, X, Y, Z, a, b, u, v, y, x) are
-floating-point values.
-The syntax for these values is an optional plus or minus sign,
-a string of digits possibly containing a decimal point,
-and an optional exponent field consisting of an ``E'' or ``e''
-followed by an optional plus or minus followed by a string of digits.
-.SH DIAGNOSTICS
-.TP 1i
-.ZN BadColor
-A value for a Colormap argument does not name a defined Colormap.
-.TP 1i
-.ZN BadValue
-Some numeric value falls outside the range of values accepted by the request.
-Unless a specific range is specified for an argument, the full range defined
-by the argument's type is accepted. Any argument defined as a set of
-alternatives can generate this error.
