Bluish is good, don't worry. A fresh coil will and should take on a blue tint once heat's been applied.
[EDIT] I should point out I'm referring to A1 Kanthal. If you're using nichrome or titanium, they may act differently? Can anyone else weigh in?

Titanium (solid) Idk about wire, but I'm assuming its the same can blue with heat. I haven't worked with too much nickel tho so I can't give any information on that.
The difference in color may be due to the one coil being lower resistance than the other and running hotter?
Yes it is A-1 kanthal and both coils were reading the same resistance, Both fire up the same time and glow evenly from inside out.
Don't worry it's a good thing and will help protect the coil. I sometimes (when I remember) torch a new coil to intentionally create that bluish hue. I think it looks beautiful.
Just to reinforce this, while it may be true that your coils gave the same reading and visually appear to be firing at the same time, this is rarely actually the case. You're always going to have some minor variance between the two. One coil getting (or losing) the blue tint before the other is confirming what your eyes alone cannot. That said, it's likely minor enough to not matter.
