Parse a color specification made up of a color constant for one of the supported color models or a control sequence which is bound to color convertible code.

Parameters:

context - the interpreter context

source - the source for new tokens

typesetter - the typesetter

primitive - the name of the invoking primitive

Returns:

the color found

Throws:

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter
