I'd like to add some of my favorites to the recommendation pool of
blues. TIDE'S IN has been a long-standing favorite and has done well
over many many years. I've also had OREGON SKIES for a few years and
it has done very well for me and looked good at conventions as well.
Both of these are light blues--the kind with real color that are not
cool whites, and not so dark that the non-initiated rest of the world
considers the color violet and not really blue.
And, if you can tolerate a tiny step away from TBs, MAUI SURF is an
excellent Border Bearded of the light blue family with a little darker
blue-violet accent and lots of ruffles, and it has grown very well
in DE and in OH.
