The royal purples, deep magentas, and rich greens of the coronation sequence possess a newfound saturation and royalty. More importantly, the shifting tones of blue throughout the film are beautifully parsed. Instead of bleeding into a singular shade, the 4K disc cleanly differentiates between the icy aqua of Elsa's magic, the deep navy of the fjords, and the pale twilight blues of the mountain peaks. The magenta and pink tones of the sunset during Anna and Kristoff’s mountain trek pop with a radiant warmth that balances the cold environments. Immersive Audio: The Dolby Atmos Upgrade
