[2] Produced by Max Martin, Oscar Holter and Bill Rahko,[3] the song is the longest ever released by the band, running at 10 minutes and 18 seconds.

Matt Doria from NME praised the track for "echoing the rhapsodic prog-rock vibes of Pink Floyd circa Dark Side of the Moon" and also noted how it marks "an ambitious step into uncharted territory for Coldplay, though not eschewing too far from [their] standard fare".

[6] Writing for Rolling Stone, Daniel Kreps described the song as a "space epic" and a "multi-suite voyage into the cosmos, with Chris Martin namechecking celestial bodies [...] along his journey to the stars".

[8] AllMusic's Neil Z. Yeung commented that "while they typically end their albums on a grand, uplifting note, ["Coloratura"] takes the prize for ambition and sheer beauty".

[9] Ella Kemp, writing for Rolling Stone UK, said that the song "might be the most dazzling thing Coldplay have ever done, a sprawling Pink Floyd-esque experiment which pays off infinitely".
