Color is not claimed as a feature of the mark.
The mark consists of a stylized drawing of what can be interpreted as one or two faces. If viewed as one face, there is a vertical separation down the middle of the face. The image can also be perceived as two side face profiles. The bottom of the face or faces meets at a point. Directly beneath the point is the wording "CHAT2TALK". Beneath the wording is the slogan "We did not invent mobile Internet voice, we make it easier to use".
CHAT TWO TALK WE DID NOT NOT INVENT MOBILE INTERNET VOICE, WE MAKE IT EASIER TO USE
