'Roja' is the feminine form of the color. You must use 'roja' when describing feminine things (like 'casa' or 'flor'), and 'rojo' when describing masculine things (like 'coche' or 'libro').
⭐ Usage Tips
Placement
In Spanish, the describing word (adjective) usually comes after the thing it describes (noun): 'falda roja' (red skirt), not 'roja falda'.

Frequently Asked Questions
Why do I see 'rojo' and 'roja'? Which one is right?
Both are correct! They mean the same color ('red'), but they depend on the gender of the thing you are describing. If you are describing a masculine thing (like a book, 'el libro'), use 'rojo'. If you are describing a feminine thing (like a flower, 'la flor'), use 'roja'. This is called 'gender agreement'.
Does 'roja' have a plural form?
Yes, to describe more than one feminine thing, you simply add an 's' to make it 'rojas'. Example: 'Las luces son rojas' (The lights are red).
