Discover the Art of French Colour Vocabulary in Autumn
As I sit here writing this blog post, I’m gazing out of my office window at the enchanting autumn scene, savouring the splendid hues of the season. This breathtaking autumn panorama has sparked my musings about colours in the French language, and how mastering French colour agreements can elevate your confidence as a learner.

Challenges of Adjectival Agreements
Have you ever found it tricky to remember the rules for adjective agreement while speaking?
In conversations, our brains are working at lightning speed. We’re not only thinking about what we want to say but also processing the other person’s words, tone, and body language. Add in the challenge of recalling vocabulary, managing pronunciation, applying grammar rules, and keeping our “English brain” at bay — it’s no wonder mistakes happen!
That’s why mastering French colour agreements can feel like such a relief. You’ll free up mental space for enjoying your conversations rather than worrying about every little ending.


In this post, we’ll delve into the world of French colour vocabulary. By mastering French colour agreements and understanding the fascinating exceptions, you’ll simplify your learning while making your French sound more sophisticated and natural.

Exceptional French Colour Vocabulary
Why not simplify your life and impress your French friends at the same time? In French, some colours are rebels — they never change form, no matter what they describe. Understanding these makes mastering French colour agreements much easier.
Rebels of the Colour World
You probably already know that orange and marron never change. They’re perfectly suited to autumn, and you can use them freely without any agreement — ever!
But that’s not all. When a colour is modified by another adjective or by a noun used as an adjective, it stays invariable. These little tricks are gems for learners who want to sound natural without overthinking.
Expanding the List
Did you know that you can expand this list? “Kaki” (khaki), “bordeaux” (maroon/burgundy), “prune” (plum-coloured), and “olive” (olive-green), are also members of this rebel gang!
The Magic of Modifiers
Another nifty trick is to use modifiers! When a colour is modified by another adjective or a noun used as an adjective, it doesn’t need to agree – youpiii! Take a look at these 16 examples; they are all “invariables” – which means they never change:
