+.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.
