Chris Bumbray from Arrow in the Head rated the film a score of 7/10, praising the film's performances, visual style and effects while noting the film's length. Bumbray summarized his review by writing, "While it's maybe a touch slow and arty for hardcore horror fans, Color Out of Space is still a handy comeback for Richard Stanley, who hasn't lost a beat." Mary Beth McAndrews from Daily Grindhouse gave the film a positive review, writing, "[Richard Stanley's] film successfully captures the madness of Lovecraft's work and is a dazzling modern interpretation. [...] Lovecraft is notoriously hard to adapt, but Stanley walks the fine line between horror and existential dread to create a successful adaptation".
Deborah Young from The Hollywood Reporter offered the film similar praise, writing, "Hitting the main plot points with well-designed SFX and some impressive night photography, Stanley's film manages to be frightening indeed, even with star Nicolas Cage's semi-farcical leavening adding some nutty laughs." Jonathan Barkan of Dread Central awarded the film three and a half out of five stars, praising the film's visual style, special effects, and soundtrack, while criticizing the film's first and third act. Nevertheless, Barkan summarized his review by stating, "Gorgeous, vibrant, and terrifying, Color Out of Space is packed with Lovecraftian creatures and cosmic infections galore. It's not perfect but goddamn is it a wild ride."
Dennis Harvey from Variety gave the film a mostly positive review, noting the film's uneven tone and Cage's "arbitrarily oddball" performance, while praising the film's otherworldly imagery, cinematography, and direction.
The Skinny's Katie Goh gave the film a rating of three out of five stars, stating that: "Colour Out of Space is at its best when Stanley goes for this subtle and intelligent filmmaking, gesturing at the horror rather than pushing it in our faces".
Howard Gorman from NME praised Stanley's welcome return, underlining the core "intense, unpredictable and harrowing moral tale," and Cage putting in his "most nuanced" turn in the last decade.
