Creates a Color object using the given color model, and with the given components.
The core color models are \f(CW\*(C`rgb\*(C'\fR, \f(CW\*(C`hsv\*(C'\fR, \f(CW\*(C`cmy\*(C'\fR, \f(CW\*(C`cmyk\*(C'\fR and \f(CW\*(C`gray\*(C'\fR.
The components of colors using core color models are between 0 and 1 (inclusive)
.ie n .IP """Black"", ""White""" 4

Return the components of the color.
.ie n .IP """$other = $color\->convert($tomodel);""" 4
.el .IP "\f(CW$other = $color\->convert($tomodel);\fR" 4
.IX Item "$other = $color->convert($tomodel);"
Converts the color to another color model.
.ie n .IP """$string = $color\->toString;""" 4
.el .IP "\f(CW$string = $color\->toString;\fR" 4
.IX Item "$string = $color->toString;"
Returns a printed representation of the color.
.ie n .IP """$hex = $color\->toHex;""" 4
.el .IP "\f(CW$hex = $color\->toHex;\fR" 4
.IX Item "$hex = $color->toHex;"
Returns a string representing the color as \s-1RGB\s0 in hexadecimal (6 digits).
.ie n .IP """$other = $color\->toCore();""" 4
.el .IP "\f(CW$other = $color\->toCore();\fR" 4
.IX Item "$other = $color->toCore();"
Converts the color to one of the core colors.
.ie n .IP """$complement = $color\->complement();""" 4
.el .IP "\f(CW$complement = $color\->complement();\fR" 4
.IX Item "$complement = $color->complement();"
Returns the complement color (works for colors in \f(CW\*(C`rgb\*(C'\fR, \f(CW\*(C`cmy\*(C'\fR and \f(CW\*(C`gray\*(C'\fR color models).
.ie n .IP """$new = $color\->mix($other,$fraction);""" 4

with \f(CW\*(C`(1\-$fraction)\*(C'\fR of color \f(CW$other\fR.
.ie n .IP """$new = $color\->add($other);""" 4
.el .IP "\f(CW$new = $color\->add($other);\fR" 4
.IX Item "$new = $color->add($other);"
Returns a new color made by adding the components of the two colors.
.ie n .IP """$new = $color\->scale($m);""" 4
.el .IP "\f(CW$new = $color\->scale($m);\fR" 4
.IX Item "$new = $color->scale($m);"
Returns a new color made by mulitiplying the components by \f(CW$n\fR.
.ie n .IP """$new = $color\->multiply(@m);""" 4
.el .IP "\f(CW$new = $color\->multiply(@m);\fR" 4
.IX Item "$new = $color->multiply(@m);"
