"Her cap is purple."

Translation: Jej czapka jest fioletowa.

[GregeG]

I always used "purpurowy" for purple.

[vytah]

The image below is labelled on Wikipedia as "Shades of purple"., but if you ask a Pole about it, they will say fioletowy:

Purpurowy refers only to certain darker and more reddish shades of fioletowy.

[immery]

isn't purpurowy more red? like the color half between red/pink and purple? It is what I have in mind when I say purpurowy. fioletowoczerwony

[wladzimirpucin]

Is 'jest' required in this sentence?

[immery]

yes.

[dont_tread_on_me]

It's probably been asked hell of a lot of times before but "jej czapka to fioletowa" is incorrect? I can only assign a noun to a noun with "to"?
