Learn German: Das Brot ist braun.

In German, adjectives only get an ending when they come directly before the noun they describe (like das braune Brot). Because braun comes after the verb ist, it acts as a predicate adjective and stays in its basic dictionary form without any extra letters.

Is Brot always a neuter word?

Yes, Brot is a neuter noun, so it uses das for the word 'the'. If you want to talk about multiple loaves of bread in the plural, the gender rules shift to use the plural 'the', becoming die Brote.

Is braun the usual way Germans talk about dark bread?

While this sentence is grammatically perfectly correct to describe color, Germans usually refer to their traditional dark breads by specific names like Graubrot (grey bread) or Schwarzbrot (black bread) rather than just calling the bread braun.
