Blue eyes are reported with notably higher prevalence in Northern and Eastern Europe than in most other studied world regions, though exact figures vary between sources.

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: Reported with notably higher prevalence in Northern and Eastern Europe than in most other studied world regions.
