Is B3 blue the same as UU1 Blue?

Why do they have to make it so hard. Yeah, I know, because if I finally get this right, I'll really appreciate the work and what I have learned. All true. I bought some in an 11 ounce can. I'm going to try it on some brackets to see how it looks and go from there. Again, I am really thankful for the help. Something in the back of my mind kept telling me not to be in such a rush to change the color. The trunk idea was a good one. Looks good.
