The color of a pretty, finished weld is nice, but people worry way too much on the color. Of course a dark grey (rough looking) weld usually is indicative of a problem, some blue color isn't going to hurt the weld at all. Any color on a weld is only surface CONTAMINATION. Many times, stainless will rust if you don't clean this contamination off.
all the welds I saw in this thread look just fine to me, even the darkest ones.

If you're looking to learn to weld by studying guys that weld manifolds for a living (or hobby), you will hear all kinds of bad habits, myths, BS, and even lies. Be careful.
