I have a 6k6GT that when i turn my radio on, it emits a sorta neon looking blue color.

the 6k6's are different brands.
i have the original totally blacked out philco 6k6's which are good put back as spare.

 I have 220degF on one 6k6, i have 245degF on the one that goes blue looking.

i moved the two 6k6's and it is infact the tube turning blue and not something about the circuit feeding it.

is this ok?

if so, how do i get more of these tubes that go blue?  looks really nice
