*AND* it is 600 degrees F, not 600 K.

Note:
600 K = 620.33 °F,
600 °F = 588.7056 K,
607.261 °F = 592.739 K, &
574.5875 °F = 574.5875 K.


That arithmetic is correct, but I'm not sure I see the point.
The temperature range for each color is rather narrow:

F C K
Full blue 560 293.3 566.5
Dark blue 570 298.9 572.0
Very dark blue 600 315.6 588.8

I was being charitable to associate any shade of blue with
any kind of 600. Reference:

The point remains, the original question was based on numerous
false assumptions.
