The symbol mark holds the values pursued by ISU Group, which are creativity, challenging spirit and customer satisfaction of the members of ISU who are preparing a new future. The solid word mark in ISU Blue, which gives a sense of youth, flexibility and reliability, and the square element in ISU Green, which represents high tech and environment, suggest the innovation and pride of ISU Group, respectively. The go-ahead shape in diagonal direction, not formulaic and stereotypical, expresses the will of ISU Group that intends to advance into future and grow into a global company.

The symbol is the most important visual element that represents ISU Group and thus strict management and control are required in use to better shape the image and heighten reliability of ISU Group.

The signature is made up of 2 elements, symbol and logotype, and plays a key role in showing ISU System at home and abroad, and thus meticulous care is required for use and management. In using the signature, no modification is allowed for any reason whatsoever, and when scaling up or down, the rules on spacing, font size and minimum size must be followed.

The color system is divided into main colors and supplementary colors. ISU Blue and ISU Green used for the symbol are main colors, while ISU Gold and ISU Silver used in specific cases and ISU Light Gray used for background are supplementary colors. The brightness and chroma may vary depending on expressive medium such as print and video, so extra care should be taken for use. As a rule, ISU colors should be used when using colors for ISU Group, and when using 4 colors/3 colors, colors that are most similar to the set colors should be accurately used.
