Resulting Definition
A Color serves as a landmark in color-space, either a
point-like landmark (e.g. burnt sienna) or a
broader region (e.g. blue). Especially when the
Color designates a broad region in color-space, it
may be defined with a specific Type (pitch, azure),
further specified by comparison to the color of a
Comparand (of/as), modified by a Color_qualifier
(light, reddish), ascribed to some Cause (from,
with) or evaluated with a Descriptor (lovely). All
color words are generally used to specify the color
of some (physical) Entity, which exhibits the
Color to some Degree (very, quite).
