NB Although the adjectives каштановые "chestnut," русые "light-brown," and белокурые "light-blond" are used with the word волосы "hair," they are not used with брови. With regard to adjectives with -бровый, note that чернобровый is widely used, светлобровый is very uncommon, and other color combinations are not used at all; theoretically, adjectives of this sort could also be formed from the phrases рыжие брови, седые брови, and белёсые брови, but in fact the standard way to describe a person with red eyebrows (or grey eyebrows, etc.) is мужчина (or женщина, девушка, etc.) с рыжими бровями, etc.
