Color is not claimed as a feature of the mark.
The mark consists of the stylized wording "NAGARAKU" and four Chinese characters "YI SI GE ER".
The non-Latin characters in the mark transliterate to "YI", "SI", "GE" and "ER" and this means "HE", "THIS", "SONG" and "SON" in English.
The wording "NAGARAKU" has no meaning in a foreign language.
