Blue is more than a color. It is a symbol of the sky, the sea, tranquility, and infinity – but also of coldness, sorrow, and longing. In art, blue has always held a special position throughout history, both as a rare and valuable pigment and as a powerful emotional element.
The Many Shades and Names of Blue
Blue appears in countless shades, each with its own name and character. From the deep, mysterious midnight blue to the light, serene sky blue, it spans a wide range of expression.
At ArtSchool.Nu, you learn to identify and mix these nuances so that you can use them effectively in your own artistic work. Knowing the origins and names of these colors can also deepen your understanding of their historical use.
Here are some of the most common shades of blue:
Sky Blue: A light and airy color reminiscent of a clear summer sky.
Navy Blue: A deep and strong tone, often associated with the sea and authority.
Royal Blue: A rich, intense hue that conveys elegance and power.
Turquoise: A blend of blue and green that evokes tropical seas and gemstones.
Azure Blue: A bright, clear tone often used to describe the color of the Mediterranean.
Midnight Blue: A dark, mysterious hue resembling the night sky.
1. Ultramarine Blue
Origin: Originally produced from the semi-precious stone lapis lazuli. The word ultramarine comes from the Latin ultra marinus – “beyond the sea” – referring to the long journey the stone made from Afghan mines to Europe. The synthetic version, invented in the 19th century, is based on aluminum silicate and sulfur.
Temperature: Cool. Ultramarine has a deep, intense blue tone with a hint of violet.
Characteristics: Known for exceptional lightfastness and depth. Its larger pigment particles give a slightly grainy texture in watercolor and a transparent quality in oil paint. In thick layers it can appear almost black. Historically, genuine ultramarine was extremely costly and reserved for important figures such as the Virgin Mary.
2. Cobalt Blue
Origin: Made from cobalt(II) aluminate. Cobalt has been used as a coloring agent for centuries, especially in glass and ceramics. The pigment was synthesized in the early 19th century.
Temperature: Cool. Cobalt blue is bright, pure, and slightly greenish in tone.
Characteristics: Highly stable and resistant to fading. Less transparent than ultramarine and with a finer particle size, it applies smoothly and evenly. Ideal for painting skies and water. Non-toxic and durable.
3. Prussian Blue (Berlin Blue)
Origin: The first modern synthetic pigment, discovered accidentally in Berlin in the early 18th century by chemist Johann Jacob Diesbach. It is a complex of ferrocyanide (iron cyanide).
Temperature: Cool. A very dark, deep blue with a greenish undertone, appearing nearly black in concentrated form.
Characteristics: Noted for strong tinting power and excellent coverage. Once revolutionary as an affordable alternative to ultramarine. Still used today, even in medicine, as an antidote to heavy metal poisoning. Can brown or shift when exposed to alkaline environments.
4. Cerulean Blue
Origin: Made from cobalt(II) stannate (cobalt and tin). Introduced commercially in the mid-19th century. The name derives from the Latin caeruleus, meaning “dark blue” or “sky blue.”
Temperature: Cool. A light, clear, slightly greenish blue reminiscent of a bright summer sky.
Characteristics: Opaque, even, and stable. Its covering power makes it well suited for opaque layers and skies.
5. Indigo
Origin: Originally a natural dye derived from Indigofera plants, especially Indigofera tinctoria. Today it is mostly synthetic.
Temperature: Cool. A deep, dark blue with a violet undertone, lying between blue and violet in the spectrum.
Characteristics: Best known as the dye used in denim. Natural indigo varies slightly depending on the plant source. It is a “vat dye” — insoluble in water until chemically reduced, then oxidized back to blue. It fades gradually over time, adding to its characteristic charm.
6. Azure Blue
Origin: The name comes from the Arabic al-lazaward, referring to lapis lazuli. Azure is not a specific pigment but rather a description of a bright, sky-like blue, historically made from lapis lazuli or azurite.
Temperature: Cool. A clear, vivid, light sky blue.
Characteristics: Associated with a cloudless sky or the Mediterranean. A general color name rather than a specific pigment.
7. Sky Blue
Origin: A descriptive color name referring to the sky’s color on a clear day. Achieved with a variety of blue pigments.
Temperature: Typically cool, though it can appear slightly warmer if mixed with a touch of yellow.
Characteristics: A familiar, peaceful color widely used in art, fashion, and design.
8. Midnight Blue
Origin: Describes the deep, dark color of the night sky. Created using indigo, Prussian blue, or a mix of deep blues and black pigments.
Temperature: Very cool, nearly black.
Characteristics: Sophisticated and formal, often used as an alternative to black in fashion and interior design.
9. Navy Blue
Origin: Named after the traditional color of Royal Navy uniforms. A very dark, almost black blue.
Temperature: Cool.
Characteristics: Classic, versatile, and timeless. Suggests authority and reliability.
10. Turquoise
Origin: Named after the gemstone turquoise. A blend of blue and green.
Temperature: Can be cool or warm depending on the mix — more blue makes it cooler, more green warmer.
Characteristics: Evokes tropical waters and coral reefs. Fresh and lively. Considered a tertiary color in color theory.
11. Petrol Blue
Origin: Named after its resemblance to crude oil or gasoline. A deep, muted blue-green.
Temperature: Usually cool, with a subtle warmth due to its depth.
Characteristics: Sophisticated and understated. Common in interior design and fashion, darker and grayer than turquoise.
12. Royal Blue
Origin: Historically linked to royalty. Said to have been created for Queen Charlotte in the late 18th century. A bright, saturated blue.
Temperature: Cool.
Characteristics: Brilliant and striking, associated with luxury and refinement.
13. Baby Blue
Origin: A pale, pastel blue commonly associated with baby clothing.
Temperature: Cool.
Characteristics: Soft and delicate, symbolizing innocence and calmness.
14. Tiffany Blue

Temperature: Cool.
Characteristics: Iconic and elegant, symbolizing sophistication and exclusivity.
15. Blue-Gray
Origin: A mix of blue and gray.
Temperature: Cool.

16. Lavender Blue / Blue-Violet
Origin: A blend of blue and violet, named after the lavender flower.
Temperature: Mostly cool, softened by the red in violet.
Characteristics: Dreamy and subtle, often linked to spirituality and imagination.
Differences Between the Shades
The primary differences between blue colors lie in:
- Hue: Whether they lean toward green (e.g., Prussian blue, turquoise, petrol blue) or violet (e.g., ultramarine, indigo).
- Saturation: Bright and pure (e.g., royal blue, cobalt blue) versus muted or grayish (e.g., blue-gray, baby blue).
- Value: Light (e.g., sky blue, baby blue) versus dark (e.g., midnight blue, navy blue).
- Origin/Pigment: Natural minerals, synthetic compounds, or plant dyes — each affecting stability, opacity, and texture.
- Temperature: Even slight traces of red or yellow alter the warmth or coolness of the hue.
Historical Color Names
In art history, several blue pigments have distinct traditional names. For example, ultramarine, made from lapis lazuli, was once extremely costly and used to emphasize sacred subjects such as the Virgin Mary’s robe.
