"No one knows what it's like To be the bad man To be the sad man Behind blue eyes"
— "Behind Blue Eyes", The Who
The color blue in eyes is a recessive genetic trait exclusive. Like most eye and hair colors lighter than black or brown, it is found mostly in Caucasian people. To actually get blue eyes, both parents genetic material must select for it. Thus it is a rare trait, which is why brown and black tend to be more likely in people's eye color. Biologically, blue eyes slightly limit the light absorbed. People with blue eyes see better in the dark (incidentally, blue is more common in the colder regions of the world where there is less light and is a common sight amongst Arctic predators), but environments with harsh light are more likely to inflict eye damage.
Blue eyes themselves are Not a Trope and as such should not be listed on any page. If you find any links to Blue Eyes, please delete them, or see if they fall under one of the actual tropes instead.
vary greatly in their meaning:
- Innocent Blue Eyes: Beautiful, innocent "baby blues" or clear, pure, and shining. Either way, a popular choice for heroes and heroines. Common with Hair of Gold, Heart of Gold.
- Icy Blue Eyes: Piercing and icy, seeming to look right through you.
- Creepy Blue Eyes: Given to particularly degenerate characters, sort of light and watery, and there are blue eyes that seem to be too open where one starts to hope they'll blink soon.
- Occult Blue Eyes: Possessing the Magical Eye. In Mediterranean countries, the Demon's Eye amulet is always blue. (Xenophobia may explain this.)
- Elemental Eye Colors: Any blue for Making a Splash and Icy Blue Eyes for An Ice Person.
