Dilute Blue and Blue? I would guess those are the same things, unless they mistakenly mean lilac and blue. Lilac is not a dilute of blue, it is a dilute of chocolate. Blue is a dilute of black.
Pretty sure dalmatian is just a variety of broken, like booted and English Spot spots. I think it's mostly random spotting in the general pattern areas? Like this guy: http://www.rabbitcolors.info/int/en/ent ... tml?id=676 More individual spots instead of blotches.
