Are these the exact official flag colours?

The hex values are close, widely used web approximations of each flag's colours. Official specifications often use Pantone or textile colour standards, so for print or manufacturing always check the country's official flag specification.

What does the layout field describe?

Layout describes the basic geometric design, such as horizontal tricolour, vertical tricolour, a cross, or a field with a canton. It is a quick way to group flags by their visual structure.

Why do so many flags use red, white, and blue?

Red, white, and blue spread widely through revolutionary and colonial history, notably from the French and American flags, and through pan-Slavic colours. They are bold, high-contrast, and easy to reproduce, which is why they recur so often.

What are pan-African and pan-Arab colours?

Pan-African colours are red, gold, green, and sometimes black, drawn from the Ethiopian flag and the early independence movements. Pan-Arab colours are red, white, black, and green. Many flags adopted them to signal regional solidarity.

Does the adopted year mean the country is that old?

No. The adopted year is when the current flag design took its present form, which is often much later than independence. Countries frequently revise their flag after constitutional changes, so a recent year does not mean a new nation.

What is the National Flag Colours Reference?

Searchable reference of national flag colours, layout, and symbolism by country, with hex colour swatches, the flag design pattern, and the year the current flag was adopted. It runs free in your browser on Gera Tools, with nothing uploaded.

Designers, quiz makers, and developers building country pickers all need quick access to flag colours. This reference lists the main colours of each national flag with hex swatches, the basic layout pattern, the adoption year, and a short note on what the design symbolises.

How it works

Each flag is described along three axes:

Colours — the dominant colours, shown as hex swatches you can copy. These are practical web approximations, not certified print specifications.
Layout — the geometric pattern, for example horizontal tricolour, vertical tricolour, cross, or canton with stripes.
Symbolism — a brief note on what the colours and emblems represent, plus the year the present design was adopted.

Filtering works on the country name and on colour words, so a search for green surfaces every flag that includes green.

Regional colour families

Flags cluster into regional colour vocabularies, which is the fastest shortcut for quiz preparation or geographical recognition:

Pan-African palette — red, gold (or yellow), green, and often black. Drawn from the Ethiopian flag and the early pan-African independence movements of the mid-20th century. Appears across West Africa, East Africa, and the Caribbean diaspora.
Pan-Arab palette — red, white, black, and green. Derives from the Arab Revolt flag of the First World War and became a signifier of Arab nationalist and post-colonial identity across the Middle East and North Africa.
Pan-Slavic palette — red, white, and blue in various arrangements. Radiates outward from the 19th-century Slavic national movements; seen across Eastern and Central Europe.
Nordic cross — a horizontal cross offset towards the hoist, used by Denmark, Norway, Sweden, Finland, and Iceland, all in different colour combinations. The cross design predates modern flag conventions.
French revolutionary legacy — the tricolour (three vertical or horizontal bands of similar-width) spread from France and became the dominant global flag layout. Many former French and British colonies adapted it.

Common use cases

Developers building country selectors: search the colour name to find all flags in a colour family, helping you group visually similar options or avoid palette clashes in a UI.
Quiz and trivia design: sort by layout to group flags of the same geometric type; adding the adoption year can build timeline-based questions.
Brand and design work: the hex values give you a starting palette for country-themed materials, though they should be reconciled with official Pantone specifications for print.

Tips and notes

For manufacturing or print, the hex values here are a starting point only — always reconcile them with the country’s official Pantone or textile flag specification. Some flags have very specific Pantone references (the UK Union Flag, for example, specifies exact Pantone values for its red and blue) and web approximations can look noticeably different in print.
