In order to construct a mapping , rather than just define it
extensionally as I did in Section
(p.
), we need a theory of how to transform a
function
into one or more pairs
.
Recall that
represents the
spectral energy distribution of a stimulus, as a function of wavelength;
represents the set of all such distributions;
represents a
set of color terms;
represents the closed interval
; and
represents a mapping
,
i.e., a color-naming mapping. I will conceptualize the mapping
as
being a composition of two mappings: one that takes us from
to what
I will refer to as a color space, and one that takes us from that
color space to
. This chapter discusses the first one of those mappings.
