Color is not claimed as a feature of the mark.
The mark consists of the word "Reprapper" depicted above the cable sword with the Chinese letters which transliterate to "RUIPU" on either side of the design element, along with an arrow between the first "R" in the word "Reprapper" and the base of the sword and an arrow between the last letter "R" in the word "Reprapper" and the base of the sword. Both arrows are pointing toward the base of the sword.
REP RAPPER
The non-Latin characters in the mark transliterate to RUIPU and this means "sharp" and "common" in English.
