KOLON's symbol mark consists of an organized shaped triangle that harmonizes both positive and negative (yin and yang) aspects with precisely coordinated seven embossed triangles and three engraved triangles which show three large triangles and three small, engraved triangles.

This place symbolizes the union between KOLON’s spirit of Inhwa (人和, Humanization), Gahwa' (家和, blissful home), Simhwa (心和, comfortable mind) and KOLON employees’ rationality, proactiveness, and cooperativeness. The imagery arising from the sculptural form of the combined triangles represents mountains, growing trees, a towering pyramid, safety and prosperity which correspond to KOLON’s corporate spirit.
