*shakes head* iv seen blue merle that are blue-nose, blue patches, light background. black merle is black patches with light grey/blue background. red/chocolate merle is self explanatory. i dont like to call what aussies come in "blue merle" because its really not. its black. any color can come in merle, except maybe?, ee yellow. i had, at one point, a blue seal brindle merle. his patches were blue brindle, and his background was orange/tan brindle. the seal was just a guess, but he wasnt "just" blue brindle, he had something else going on. i didnt get any pictures of his weird background and brindling, because my camera was crappy and every picture didnt SHOW what i could see with my own eyeballs ><
