Abstract
Structuralism, as I will use the term, is the view that phenomenal character is fully determined by the
similarity relations between experiences – that, for instance, the way an orange experience feels is
entirely a matter of its relational profile within the space of color experiences. This theory has been
criticized because it seems to leave out what is sometimes referred to as the intrinsic character of
experience. However, these critiques have failed to convince numerous scholars, largely due to their
reliance on intuition, a tool that many consider unreliable. Here, I present two objections to
structuralism that rest on firmer ground. The starting point is certain structural features of color
experience that are widely accepted in the science and philosophy of color, despite some criticisms that
I discuss and reject. Then, playing the structuralist game through and through, I defend the claim that
the structure of color experience is incompatible with structuralism, which is ironic if one considers that
structuralism should be expected to account at least for the structural features of experience. I formulate
two arguments to show this incompatibility: one focusing on the unique hues (red, green, yellow, and
blue), and a second focusing on the rule regulating how the pure colors (red, green, yellow, blue, black,
and white) combine in the composite colors. I consider some possible counterarguments, provide
rebuttals, and conclude that structuralism should be rejected.
