+    - fillets meeting with psa and humppake 
+       - some ideas to think about:
+               - show the nodes (without connections) before
+                 showing the full graph in each trial
+                 --> search time eliminated
+               - color all nodes differently and interpolate
+                 the color over the connections -->
+                 should be even less ambiguous
+                 (probably not usable for showing the
+                 superiority of fillets)
+       - conclusion:
+               - experiments first
+       
+    - read the book "Robert M. Boynton: Human Color Vision,
+      New York: Holt, Rinehart and Winston, 1979." Notes:
+       - sensitivity regulation for lightness is well known:
+         the size of pupil, pigment bleaching, and receptor 
+         sensitivity adapt the sensitivity
+       - however, chroma sensitivity as a function of chroma range
+         is not directly considered in the book
+       - contours play a crucial role in color vision:
+         colors are averaged over regions separated by contours
+       - B cones do not participate in contour perception
+         (there are very few B cones in the fovea)
+       - colors whose R-G and R+G responses are identical
+         are discriminated better if a small gap is inserted
+         between the fields so as to enable contour perception
+
