AllMusic gave the album a positive review saying that "the band firing on all cylinders with a meaty, 12-song set that pairs unrelenting aggression with expansive arrangements and introspective lyrics.
"[10] Distorted Sound scored the album 8 out of 10 and said: "Ultimately then, even if Color Decay did feel like a bit of a sure thing given the band's recent form, the delivery here is exquisite.
This is everything one could ask of a modern metalcore record; hugely melodic and memorable and yet often just as searingly heavy, with all this elevated by an intense emotional resonance, it's yet another home run from a band who have kept in step with the evolution and growth of the genre in a manner that many others could only dream of.
"[11] John Bacon of HM stated "An emotional work of art, Color Decay is a record for both diehard fans and those who are new to this scene.
"[13] New Noise gave the album 4 out of 5 and stated: "While not their best release, they certainly put their best foot forward on Color Decay, delivering many songs that fans expect, and some that they may not.
If it were up to me, they would start a side project for the rock and melancholic tracks and stick to the heavy stuff for The Devil Wears Prada, or switch to EPs and really focusing in on one sound for each.
