Every Sun Color In The DC Universe Explained

Warning! This submit incorporates SPOILERS for Supergirl (2026)

James Gunn’s DCU already options a number of suns with totally different colours, which drastically have an effect on heroes like Superman and Supergirl. As seen within the new Supergirl film starring Milly Alcock because the titular Lady of Metal, Kara Zor-El travels the galaxy, visiting different worlds past her cousin’s adoptive homeworld of Earth. As such, many of those worlds orbit distinctive suns with various sorts of photo voltaic radiation.

Within the DC Universe seen within the comics, a number of solar colours have been featured at totally different factors, and each can have an effect on Kryptonian physiology otherwise. Over the many years, the variety of totally different stars and colours seen on the web page has been fairly spectacular, starting from blue, white, orange, and extra. Nonetheless, the brand new DCU to this point solely has three totally different confirmed colours (to this point).

Protecting that in thoughts, this is all the pieces we learn about every confirmed solar colour within the DCU after watching 2026’s Supergirl, and the way they will change Kryptonian powers and talents.

Yellow Solar

Unquestionably, yellow suns are a very powerful (and most frequent) celestial physique within the DC Universe, the supply of the powers and talents usually related to Superman, Supergirl, and Kryptonians usually. Yellow suns are youthful stars in comparison with the purple solar of Krypton, explaining why its photo voltaic radiation impacts Kryptonians so otherwise, turning them into superhuman beings with a full vary of powers (flight, tremendous power, sturdiness, velocity, warmth imaginative and prescient, freeze breath, and so on.)

Kryptonians like Superman and Supergirl are continually absorbing photo voltaic power like dwelling batteries, and concentrated doses of yellow daylight can quickly velocity up their therapeutic as seen in 2025’s Superman with David Corenswet’s Man of Metal after taking some main hits from the Hammer of Boravia (Ultraman). Likewise, the yellow solar has been featured as a serious supply of regeneration even from the brink of dying in comics and previous films (like when Superman survived a direct hit from a nuke following direct daylight publicity in Daybreak of Justice).

Moreover, the advantages and benefits of yellow daylight lengthen past Kryptonians to different alien species from the comics additionally born on worlds with purple daylight (like Daxamites), although differing physiologies can result in totally different powers and weaknesses.

Crimson Solar

If a yellow solar unlocks a Kryptonian’s full potential, a purple solar does the precise reverse. Crimson stars are older than yellow ones, and Krypton itself orbited a purple solar for many of its historical past. As such, Kryptonians developed as a race not in contrast to bizarre people, albeit with extra superior applied sciences and cultures. Comparatively, purple suns emit a lot decrease photo voltaic radiation, that means a Kryptonian present beneath a purple solar has no powers in any respect. It is solely when beneath a yellow solar that their powers and talents emerge.

This explains why Kara Zor-El’s Supergirl frolicked on worlds orbiting purple suns, each within the unique Girl of Tomorrow comedian by Tom King and Bilquis Evely, in addition to the DCU’s new Supergirl film, which took a lot of its inspiration from the critically acclaimed 8-issue collection. With a purple solar, Kara was in a position to occasion and get drunk when she in any other case could not with an elevated metabolism beneath yellow daylight. Nonetheless, the trade-off is that she will additionally expertise ache and be injured identical to any human.

This consists of Krypto the Tremendous Canine, which is why the Kryptonian canine was struck by a poisoned arrow by Krem of the Yellow Hills. The purple solar additionally explains why Kara wanted her personal ship, as she was unable to fly till reaching a yellow solar’s neighborhood. Within the comics, a number of villains have been recognized to make use of weapons using purple photo voltaic radiation and prisons towards Superman and his cousin, significantly Lex Luthor. One has to surprise if the DCU’s model will ever implement the identical.

Inexperienced Solar

Final however not least, inexperienced suns have one of many extra uncommon histories in DC Comics, seeing how their results have modified over time. Throughout the Silver Age, a inexperienced solar was primarily one other sort of depowering star like reds, stopping Kryptonians like Superman and Supergirl from utilizing their skills.

Nonetheless, issues modified with 2022’s Girl of Tomorrow. Tom King reinvented the idea by introducing a star that had been infused with Kryptonite, making its inexperienced daylight lethally poisonous for Kryptonians due to the irradiated items of their destroyed homeworld. The longer Kryptonians remained uncovered, the extra they have been poisoned by the poisonous photo voltaic power.

Within the Girl of Tomorrow miniseries, Supergirl and Ruthye have been transported to the world of Barenton, a synthetic planet created as a lure for Superman. In response to Kara, the Man of Metal claimed his time on the world was his “closest brush with dying”, which was really saying one thing after combating Doomsday. Nonetheless, Superman was solely trapped on Barenton for 45 minutes earlier than he was saved by the Justice League.

Conversely, Supergirl was pressured to endure the intense ache and wait out Barenton’s solar for 10 hours till it lastly set. Likewise, the world was additionally stuffed with predatory alien dinosaurs whom Ruthye needed to keep at bay as finest she might whereas defending an incapacitated Kara.

Whereas the DCU adapts Barenton and its inexperienced solar for the brand new Supergirl film, there have been some key modifications. Not solely have been there no dinosaurs, however Barenton additionally had a yellow solar which rose the second the inexperienced solar set, restoring and therapeutic Kara instantly after and permitting her to avoid wasting Ruthye, who’d been captured by the Brigands whereas she was out of fee.

With yellow, purple, and inexperienced suns now established on-screen within the DCU, it will likely be fascinating to see how Kryptonian mythology continues to broaden when and if extra colours debut in future tasks. In spite of everything, there are many colours from the comics nonetheless ready within the wings (white, black, violet, orange, blue, and extra). Consequently, there’s loads of room to function these different alternate solar colours as James Gunn’s universe expands, particularly with each Superman and Supergirl confirmed to look subsequent yr in 2027’s Man of Tomorrow.

Supergirl is now enjoying in theaters from DC Studios.
