I'd have to play with it to see, but off the top of my head . . .

In Lightroom, I would boost the color temp to about 6500K and then increase the blue saturation. If that didn't give me the result I want, I would go to PS and work the blue and red/orange separately either on layers or using select color range. From there, I'd just have to play.

Don't get me wrong, it is really nice with the pastel colors just as it is.
