The Colourful Viking Age: How Natural Pigments Shatter the Myth of the Grey North

November 1, 2026

Quick Facts About Viking Dyes

The Colour Palette: The Vikings had three primary colours at their disposal — woad (blue), madder (red), and weld (yellow) — which they could mix to create countless shades.
Dyeing Techniques: A distinction was made between fugitive (surface) and permanent dyes. Many plants required a mordant (a fixative such as alum or iron) to bind to the fibres.
Fibre Differences: Wool absorbed natural pigments excellently, while linen was considerably more difficult to dye due to its plant-based structure, making it rarer in archaeological finds.
Regional Preferences: Archaeological remains show that blue and green were popular in Scandinavia, red dominated in the Danelaw (England), and purple was beloved in Ireland.

Introduction: The Myth of the Grey North

When we think of Vikings, films and series often show us grey and drab imagery: dark clothing, rough wool, and a lack of colour. This sombre image fits neatly with the stereotype of the brutal, muddy warrior — but archaeological discoveries tell a completely different story.

The Vikings had a surprisingly broad colour palette. They used both local flowers, plants and lichens as well as precious imported raw materials to embellish their clothing. Fashion may not have changed yearly back then, but colours played a crucial role in the daily appearance, status and identity of Norse society.

The Chemistry Behind the Viking Dye Bath

How did the Vikings dye their clothing? Transforming raw wool or linen into a colourful garment was a complex process that required deep knowledge of nature. The Vikings made use of natural dyes, which were bound to textile fibres in various ways.

Some pigments coloured the fibres only superficially — the so-called fugitive dyes — and faded quickly through sunlight and washing. Other dyes formed a direct chemical bond with the fibres and were far more durable. These permanent dyes were subdivided into substantive dyes (which worked directly without additional additives) and adjective dyes. This latter group required a mordant (a fixative such as alum, iron or tannin) to anchor the colour permanently to the fibre.

The final colour result could be subtly influenced by the use of modifiers, such as lime, cream of tartar or urine (ammonia), with which the dyer adjusted the pH of the bath. The temperature of the dye bath and the original colour of the wool — which naturally varied from white and grey to deep brown — also determined the intensity of the final result.

Science in the Lab: How We Rediscover the Colours

Much of our knowledge about Viking dyes comes from archaeological finds, particularly from richly furnished elite graves. However, studying these ancient textile remains is an enormous challenge. The soil in which the fabrics were buried often contained metals and tannins itself, causing most textile fragments to appear uniformly brown or black when excavated.

Fortunately, modern science offers a solution. Thanks to advanced techniques such as liquid chromatography, researchers can discover the exact chemical fingerprint of the original pigments. Because each dye absorbs light in a unique way, chemists can compare the patterns with known historical plant substances. Even when colours have completely faded into the ground over a thousand years, the laboratory reveals how vibrant the clothing once was.

The Viking Age Palette: From Woad to Walnut

By cleverly mixing the three primary colours and layering them over each other, the Vikings created a rich range of fashionable shades.

Blue from the Coastal Regions

Blue was one of the most prized colours and was obtained from woad (Isatis tinctoria). This plant, recognisable by its bluish leaves and small yellow flowers, grew in Scandinavia particularly along coastlines, where rotting seaweed provided nutrient-rich soil.

Making the blue dye was an intense and unpleasant process. The leaves were finely chopped, crushed and rolled into balls to dry. These balls were then dissolved in fermented urine. The ammonia in the urine released the indigo pigment. When the clothing was removed from the vat, it was first greenish; only through exposure to oxygen in the open air did the fabric oxidise to a deep, permanent blue. Finds from rich graves such as Mammen (Denmark) and trading hubs like Jórvík (York) show that blue was widespread — even undergarments were dyed with it.

The Precious Red

Red was obtained from the roots of madder (Rubia tinctorum). The older the plant, the more intense the red pigment in the roots became. Because madder was naturally scarce in cold Scandinavia, this was a true status symbol. The plant or dyed fabrics were imported on a large scale from warmer regions such as Germany, France and the British Isles. Red was therefore reserved particularly for the wealthier layers of the Viking population.

Orange and the Word 'Bleikr'

For a warm, bright orange hue, dyers used the roots of sweet woodruff (Galium mollugo), a plant that was common in southern Scandinavia. Although the colour could fade to yellow or soft pink over time, freshly dyed fabric gave a vibrant hue. In Old Norse, the word bleikr was likely used to describe this specific, warm colour — a shade that was compared at the time to the yolk of a healthy hen's egg.

An Abundance of Yellow Shades

Yellow was by far the easiest colour to produce, as numerous local plants were available for it:

Heather (Calluna vulgaris): Grew abundantly on the Danish heathlands and produced a soft, subtle yellow colour.
Chamomile (Matricaria perforata): Was widespread and gave a darker, warmer yellow tint, though this common variant was probably less favoured by the elite.
Tansy (Tanacetum vulgare): Stood out with its bright, button-like flowers along roads and beaches and was a reliable source for quick yellow dyeing.
Weld (Reseda luteola): This plant was rarer in the north and grew mainly along coasts, but produced an extremely bright, almost lemon-yellow colour that was highly sought after.

Green, Purple and Dark Shades

Pure green was sometimes obtained directly from the greater knapweed (Centaurea scabiosa), a plant from dry grasslands. Often, however, dyers chose to take a more complex route: they dyed the wool first in a blue woad bath and then in a yellow bath of weld or tansy to achieve a deep, rich green shade.

Purple was obtained from specific lichens, such as Ochrolechia tartarea. Notably, many purple textile remains have been found in Ireland, which may point to a strong regional preference or easy access to these specific mosses. For the deepest shades, such as dark brown and black, walnut shells were used. When these shells were combined with iron-rich groundwater or iron slag from the smithy, a very dark, almost jet-black colour resulted.

Summary: Fashion as Identity

The grey, colourless Vikings of popular culture turn out to be a stubborn myth. Thanks to the natural wealth of their own environment and their extensive trading networks, inhabitants of the Viking Age dressed in surprisingly colourful attire.

While the absolute elite made an impression with shiny silk and deep-red madder from distant lands, even the ordinary farmer or merchant could adorn his woollen cloak with the bright blue of woad or the vibrant yellow of tansy. Fashion in the early Middle Ages was a powerful instrument: it showed your wealth, your origin and your status in the cosmos.

Historical Style Guide for Textiles

Want to assemble a historically accurate Viking outfit? Combine a linen underdress or tunic in natural, unbleached colour with a woollen overdress or cloak dyed in a warm plant tint, such as the brick-red of madder or the deep blue of woad. Use wool in diamond twill or herringbone weave to make the uptake of the natural pigments shine even more beautifully.
