How does the spelling change in French when you put a colour after feminine word?

You're touching on a fascinating aspect of French grammar!

The basic rule is that adjectives in French agree in gender and number with the noun they modify. This means that if the noun is feminine, the adjective also needs to be feminine. However, color adjectives in French follow a slightly different pattern:

Here's the breakdown:

1. Most color adjectives end in "-e" in the feminine form:

* Example:

* Rouge (masculine) becomes rouge (feminine) - Red

* Bleu (masculine) becomes bleue (feminine) - Blue

2. There are a few color adjectives that do not change for the feminine:

* Orange, beige, rose, mauve, gris, marron, and turquoise remain the same regardless of the gender of the noun.

Here's an example to illustrate:

* Une robe rouge (A red dress) - "Robe" is feminine, so the adjective "rouge" takes the feminine form.

* Un chapeau orange (An orange hat) - "Chapeau" is masculine, so the adjective "orange" remains unchanged.

Important Note: The plural form of color adjectives in French is always the same, regardless of gender. For example, "des robes rouges" (red dresses).
