Accepted Answer

Hi Dragana,
Yes 'violet' refers to the colour here :
J'adore le violet , c'est très joli. (I love purple it's a beautiful colour)
You would use 'c'est' + adjective in the masculine form for general comments.
Le bleu, c'est beau mais froid comme couleur dans une chambre.
( Blue is a beautiful colour but cold for a bedroom.)
J'ai peint ma salle à manger en jaune, c'est très gai. (I painted my dining room in yellow , it's very cheerful)
I agree with Chris on the haircut it is most specific here.
Hope this helps!

Answer

I guess it is because it is anything in violet, not a specific color. You would probably say:
Tu aimes la couleur de mon pull? -- Oui, il te va bien.
Concerning the haircut: it is a specific haircut, namely yours and not any haircut in general. Hence "elle".
-- Chris (not a native speaker).

Answer

Or, Oui, elle te va bien. If you want to refer to the specific color of the sweater. 
-- Chris.
