Is orange masculine or feminine in French?

Both, depending on what it is doing. The fruit is feminine: une orange, deux oranges. The colour is an invariable adjective with no masculine or feminine form at all: un pull orange, une jupe orange, des gants orange.

Which French colours never change?

Those borrowed from the name of an object: orange, marron, cerise, citron, olive, turquoise, noisette, crème, chocolat, kaki, argent and or. Any colour written with two words is also invariable, such as bleu clair, vert foncé and bleu marine.

Why is it des yeux bleus but des yeux bleu clair?

Because clair turns the colour into a two-word expression, and French freezes the whole expression. On its own bleu is a normal adjective and agrees; as soon as it is modified, both words stop taking endings.

Do colour adjectives go before or after the noun in French?

After, always: une voiture rouge, des cheveux bruns. If another adjective is also present it takes its usual position, so you get une belle voiture rouge with the colour still at the end.

How do you say colours as nouns in French?

Add a masculine article: le bleu, le rouge, un vert très vif. The gender is masculine regardless of what is being coloured, and this is also the form you use after en: elle s'habille en noir.

French Colour Adjectives: Agreement, Invariable Colours, and Where Orange Fits

Written by Camille Laurent, Lead French Curriculum Editor · Reviewed May 2026

Most French colour adjectives agree with the noun in gender and number, so une robe verte and des rideaux verts. But colours borrowed from the name of an object — orange, marron, cerise, turquoise — never change, and neither does a colour described by two words, such as bleu clair. Knowing which group a colour belongs to is the whole of this topic.

Elle porte une robe verte et des chaussures marron.

She's wearing a green dress and brown shoes.

What it is

A colour adjective is an ordinary adjective, so the default is that it agrees: it takes an -e for a feminine noun and an -s for a plural one. The complication is that French has kept using the names of fruits, stones and animals as colours, and those words never stopped being nouns. A noun cannot agree with another noun, so it simply stays as it is.

un pull vert, une veste verte, des gants orange — a green jumper, a green jacket, orange gloves.

How to spot it

Ask whether the colour is also a thing you could hold. Orange, marron, cerise, citron, olive and noisette all name objects, and all stay frozen. Vert, bleu, noir and blanc name nothing but the colour, so they agree.

une voiture noire — a black car (agrees)
des yeux noisette — hazel eyes (invariable)
une chemise blanche — a white shirt (irregular feminine)
des murs bleu clair — light blue walls (two words, invariable)

Rose, mauve, pourpre, fauve and écarlate began as nouns too, but they have been colour words for so long that French now treats them as full adjectives: des joues roses.

Colour Adjective Agreement Quick Reference

blanc	blanche	blancs / blanches	irregular feminine
violet	violette	violets / violettes	irregular feminine
roux	rousse	roux / rousses	irregular feminine
rouge, jaune, rose	unchanged	rouges, jaunes, roses	already ends in -e, plural only
orange, marron, turquoise	unchanged	unchanged	invariable, from a noun
bleu clair, vert foncé	unchanged	unchanged	invariable, two words

Common Colour Adjective Agreement Examples in French

The four behaviours, each with the colours that belong to it:

Colours That Agree Normally

un manteau vert: a green coat
une porte verte: a green door
des volets verts: green shutters
des feuilles vertes: green leaves

Vert, bleu, noir, gris and brun follow the ordinary adjective pattern with no surprises at all.

Colours with an Irregular Feminine

un mur blanc, une maison blanche: a white wall, a white house
un rideau violet, une fleur violette: a purple curtain, a purple flower
un chat roux, une chatte rousse: a ginger cat (m), a ginger cat (f)
un ciel gris, une journée grise: a grey sky, a grey day

These follow the same irregular feminines as other adjectives: -c becomes -che, -et becomes -ette, -x becomes -sse.

Colours That Never Change

des gants orange: orange gloves
une jupe marron: a brown skirt
des lèvres cerise: cherry-red lips
une nappe turquoise: a turquoise tablecloth
des yeux noisette: hazel eyes

Each of these is really a noun standing in for a phrase: des gants orange means gloves the colour of an orange.

Two-Word Colours

des yeux bleu clair: light blue eyes
une robe vert foncé: a dark green dress
des chaussettes bleu marine: navy blue socks
des rideaux vert pomme: apple-green curtains

As soon as a second word joins the colour, the whole expression freezes, even if the first word would normally agree.

How Colour Agreement Works

One default, three exceptions, and a reason behind each of them.

The Default Is Full Agreement

A colour is an adjective, so it takes the feminine -e and the plural -s like any other. Un sac noir, une valise noire, des sacs noirs, des valises noires. If nothing about the colour is unusual, this is what happens.

Les portes sont bleues.

The doors are blue.

Adjective in, adjective out.

A Colour Borrowed from a Noun Stays a Noun

Orange, marron, cerise, citron, olive, crème, chocolat, kaki and noisette all name something. When French uses one as a colour it is shorthand for de la couleur de, and a noun buried in that phrase has nothing to agree with.

Elle a acheté deux chemises orange.

She bought two orange shirts.

Still a noun, still frozen.

But a Few Have Crossed Over Completely

Rose, mauve, pourpre, fauve and écarlate started out the same way and lost their connection to the object. French now counts them as ordinary adjectives, so they take the plural -s.

des chaussures roses et des rideaux mauves

pink shoes and mauve curtains

Five ex-nouns that now agree.

Two Words Means No Agreement at All

Adding a modifier — clair, foncé, vif, pâle — or a second colour makes the expression a unit, and the unit is invariable. This applies even to colours that would otherwise agree, which is why des yeux bleus becomes des yeux bleu clair.

une veste bleu foncé et une écharpe bleu-vert

a dark blue jacket and a blue-green scarf

Two words, zero endings.

Colours Come After the Noun

Unlike English, French puts the colour behind the noun it describes, along with most adjectives of shape, origin and category. The only thing that ever comes between them is a modifier belonging to the colour itself.

une longue robe rouge

a long red dress

Noun first, colour second.

Common Mistakes with Colour Adjective Agreement

Incorrect: des gants oranges — orange gloves

Correct: des gants orange — orange gloves

Orange is the name of a fruit doing duty as a colour, so it stays invariable. The plural -s only appears when orange is the fruit itself: j'ai acheté des oranges.

Incorrect: une chemise blanc — a white shirt

Correct: une chemise blanche — a white shirt

Blanc has an irregular feminine in -che, like franc and sec. Adding a plain -e would give blance, which does not exist.

Incorrect: des yeux bleus clairs — light blue eyes

Correct: des yeux bleu clair — light blue eyes

A colour described by two words is invariable as a block. Neither half takes an ending, even though bleu on its own would agree.

Incorrect: des écharpes rose — pink scarves

Correct: des écharpes roses — pink scarves

Rose is the exception to the flower-and-fruit rule. Along with mauve, pourpre, fauve and écarlate it has been absorbed as a true adjective and agrees like any other.

Compound Colours, Colour Nouns, and Two Colours at Once

Three situations where the basic rule needs a second look before you decide on an ending.

Colours modified by another word

Clair, foncé, vif and pâle turn a colour into a two-word expression, and the whole expression becomes invariable. So does a colour qualified by a noun, such as bleu ciel or vert pomme.

des chemises bleu clair: light blue shirts
une jupe vert foncé: a dark green skirt
des murs jaune pâle: pale yellow walls
des rideaux bleu ciel: sky blue curtains

Compare des chemises bleues with des chemises bleu clair: the same adjective, two different behaviours, decided entirely by the extra word.

Colours used as nouns

Put an article in front of a colour and it becomes a masculine noun, whatever the thing it describes might have been.

Le bleu te va bien.: Blue suits you.
Le rouge est ma couleur préférée.: Red is my favourite colour.
Il est habillé en noir.: He's dressed in black.
un vert très vif: a very bright green

This is why you say le vert and not la verte even when talking about the colour of une porte.

Two colours on one object

When several objects each carry a single colour, the adjectives agree. When each object carries both colours at once, they stay singular.

des drapeaux bleus et rouges: blue flags and red flags
des drapeaux bleu et rouge: flags that are blue and red
des maillots noir et blanc: black-and-white shirts

The distinction is real but subtle, and in speech nobody can hear it. Writers who want to be unambiguous rephrase.
