+    According to "Principles of Color Technology" by Roy S. Berns, it is a myth
+    that "CIELAB was recommended for large color differences and that CIELUV was 
+    recommended for small color differences."  It is also a myth that "CIELAB is 
+    recommended for reflecting samples while CIELUV is recommended for sources 
+    and displays."
