Amber eyes are a solid color with a strong yellowish/golden or russet/coppery tint, which may be due to a yellow pigment called [[lipochrome]]  (also found in green eyes).<ref>[http://www.hhmi.org/cgi-bin/askascientist/highlight.pl?kw=&file=answers%2Fgenetics%2Fans_044.html Howard Hughes Medical Institute: Ask A Scientist] {{webarchive|url=https://web.archive.org/web/20100901150309/http://www.hhmi.org/cgi-bin/askascientist/highlight.pl?kw=&file=answers%2Fgenetics%2Fans_044.html |date=1 September 2010 }}.

Although hazel eyes may contain specks of amber or gold, they usually tend to have many other colors, including green, brown, and orange. Also, hazel eyes may appear to shift in color and consist of flecks and ripples, while amber eyes are of a solid gold hue. Even though amber is similar to gold, some people have russet- or copper-colored amber eyes that are mistaken for hazel, though hazel tends to be duller and contains green with red/gold flecks, as mentioned above. Amber eyes may also contain amounts of very light gold-ish gray.

The eyes of some pigeons contain yellow fluorescing pigments known as [[pteridine]]s.<ref>{{cite journal |author=Oliphant LW |title=Observations on the pigmentation of the pigeon iris |journal=Pigment Cell Res. |volume=1 |issue=3 |pages=202–8 |year=1987 |pmid=3508278 |doi=10.1111/j.1600-0749.1987.tb00414.x }}</ref> The bright yellow eyes of the [[great horned owl]] are thought to be due to the presence of the pteridine pigment [[xanthopterin]] within certain [[chromatophore]]s (called xanthophores) located in the iris stroma.<ref>{{cite journal |author=Oliphant LW |title=Crystalline pteridines in the stromal pigment cells of the iris of the great horned owl |journal=Cell Tissue Res. |volume=217 |issue=2 |pages=387–95 |year=1981 |pmid=7237534 |doi=10.1007/BF00233588 |s2cid=8061493 }}</ref> In humans, yellowish specks or patches are thought to be due to the pigment [[lipofuscin]], also known as lipochrome.<ref name=Lefohn/> Many animals such as canines, domestic cats, owls, eagles, pigeons, and fish have amber eyes, whereas in humans this color occurs less frequently. Amber is the third-rarest natural eye color after green and gray, occurring in 5% of the world's population.<ref>{{Cite web|title=Amber eyes|url=https://www.allaboutvision.com/eye-care/eye-anatomy/amber-eyes/|access-date=2021-05-09|website=All About Vision|language=en-us}}</ref> People with amber-colored eyes are found in [[Europe]], and in fewer numbers in the [[Middle East]], [[North Africa]], and [[South America]].<ref>{{Cite journal |last1=Ruiz-Linares |first1=Andrés |last2=Adhikari |first2=Kaustubh |last3=Acuña-Alonzo |first3=Victor |last4=Quinto-Sanchez |first4=Mirsha |last5=Jaramillo |first5=Claudia |last6=Arias |first6=William |last7=Fuentes |first7=Macarena |last8=Pizarro |first8=María |last9=Everardo |first9=Paola |last10=de Avila |first10=Francisco |last11=Gómez-Valdés |first11=Jorge |last12=León-Mimila |first12=Paola |last13=Hunemeier |first13=Tábita |last14=Ramallo |first14=Virginia |last15=Silva de Cerqueira |first15=Caio C. |date=2014-09-25 |title=Admixture in Latin America: Geographic Structure, Phenotypic Diversity and Self-Perception of Ancestry Based on 7,342 Individuals |journal=PLOS Genetics |volume=10 |issue=9 |pages=e1004572 |doi=10.1371/journal.pgen.1004572 |issn=1553-7390 |pmc=4177621 |pmid=25254375 |doi-access=free |bibcode=2014PLOSG..10.4572R }}</ref>
