Juri, those are really interesting color patterns.  On the first, apparently there are both yellow and violet patterns, both distributed roughly the same. 
I think the "Umbrata" pattern can take quite a variety of forms--including pigmented vein patterns radiating out across the fall, washes of color down the haft, and upper fall "washes" (borrowing a term used in painting).  Here's an example of an Umbrata restricted to a zone across the haft only--this comes from ROMANTIC EVENING.
