Figure 4.

(A–C) The dress body and lace matching data (two points per observer) labeled according to dress color names. Dress body matches are squares, circles, and diamonds. Dress lace matches are differently oriented triangles. (D–F) Same data as in (A–C) labeled according to disk color names, but note that two observers (who named the disks B/Gr and B/P) are omitted from this plot as they were excluded from the corresponding analyses. Black dashed line indicates the Planckian locus. The red dotted line is the first PC of the dress body matches. The yellow dot-dash line is the first PC of the dress lace matches.
