Also described as: chestnut eyes
A warm mid-to-deep brown, generally more visibly warm and less black-appearing than dark brown, often with clearly visible texture and radial fibre structure up close. This is the broadest and most populous of the eye-colour categories, and the range within it is correspondingly wide — from a light-leaning brown that borders on light brown, through to a deep brown that only just reads as separate from dark brown. Most classification systems treat all of that as one category.
typical range
An illustrative approximation — real brown eyes vary continuously in depth and warmth.
Commonly warm (reddish or golden undertone); occasional neutral-brown examples.
Amount of visible fleck/texture, and how warm vs neutral the base tone reads.
Generally the most stable of all the categories, because the appearance comes primarily from pigment absorption rather than from scattering. Warmth becomes more visible in bright, warm-coloured light, and the fibre texture of the iris is far easier to see in direct sun than under indoor lighting — but the underlying colour reading does not shift the way a blue or hazel iris does.
Phone HDR processing commonly boosts warmth/saturation, exaggerating how golden brown eyes appear in photos.

Brown is widely reported as the most common broad eye-colour category worldwide, though this is a general summary rather than one precise, universally comparable measurement.
This is a broad-category, worldwide summary statement, not a precise percentage. It does not break down brown into dark brown/brown/light brown, and doesn't specify which populations or studies it synthesises.
Styling ideas below are optional and editorial — never rules, and never a claim that one colour choice is objectively correct for anyone.
Confidence: high. Geographic scope: Widely reported as common across most world regions.
