Colours (sininen, keltainen, ruskea)

Finnish Colours Are Ordinary Adjectives

A colour word behaves exactly like iso or uusi: it agrees with the noun it describes, and it takes the same endings. Nothing about colour is special in Finnish grammar.

You already know valkoinen, punainen, vihreä and musta from the agreement lesson — with these six, the everyday set is complete.

The -nen Colours

Sininen, keltainen, valkoinen and punainen all end in -nen, which is one of the most common noun and adjective endings in the language. Words of this shape change their stem before an ending — sininen becomes sinise- — so a blue flower is sininen kukka but blue flowers will be sinisiä kukkia.

You do not need those forms yet. What matters now is recognising the -nen family, because you will meet it in hundreds of other words.

Pink Is a Compound

Vaaleanpunainen is literally pale-red: vaalea (pale) in the genitive, glued onto punainen. Finnish builds colour shades this way rather than borrowing new roots, and once you see the pattern you can read tummansininen (dark blue) or vaaleanvihreä (light green) without ever being taught them.

Two That Do Not Bend Much

Harmaa and oranssi are the odd ones. Harmaa ends in a long vowel and oranssi is a recent loanword, so both keep their shape more stubbornly than the -nen colours do.
