David Bowie's Eye Color: Heterochromia or Anisocoria?
The irises matched; the pupils did not.

What color were David Bowie's eyes?
Both of David Bowie's irises were blue, often reading blue-gray in photographs. The famous mismatched effect came from the much larger pupil in his left eye, not from one blue iris and one brown iris. The Open University identifies the pattern as anisocoria: unequal pupil size. That distinction turns one of rock's most repeated eye-color claims into a more interesting story about perception.
Why it was anisocoria, not heterochromia
Heterochromia describes a difference in iris pigmentation. Anisocoria describes pupils that are different sizes. Accounts trace Bowie's permanently dilated left pupil to an eye injury during a teenage fight in 1962. Because the pupil is black, a larger pupil covers more of the visible iris and makes that eye look darker, especially in dim light or a high-contrast portrait.
Why the effect changed from photo to photo
Pupil size, lighting direction, film stock, exposure and retouching all changed how dramatic the difference appeared. A dark studio portrait could make the dilated pupil merge with shadow; a bright close-up could reveal more of the blue iris. Those changes did not mean Bowie's iris color was changing—they changed how much color the camera recorded.
A useful eye-health distinction
Long-standing anisocoria can have several causes, but a new or sudden pupil-size difference can require prompt medical assessment, particularly with pain, headache, drooping eyelid, double vision or injury. A celebrity's documented history is not a self-diagnosis guide. If your pupils suddenly look unequal, contact an eye-care professional or urgent medical service.

Did David Bowie have two different colored eyes?
No. His irises were both blue; one permanently enlarged pupil made the left eye look much darker.
Did David Bowie have heterochromia?
The best-supported explanation is anisocoria, or unequal pupil size, rather than heterochromia, which refers to different iris pigmentation.
What caused David Bowie's unequal pupils?
Published accounts connect the permanently dilated left pupil to an eye injury during a fight in 1962.
Can unequal pupils make eye colors look different?
Yes. A larger black pupil leaves less visible iris and can make that eye look darker, especially in shadow or high-contrast photography.
