O&M is the abbreviation for Operation & Maintenance.
The basic color of the Xi logo is ‘PEACOCK BLUE’, suggesting a sense of intelligence, refinement, and delicacy, and the color representing the most sophisticated. The basic color creates a luxurious image when, combined with a gold background, conveys a deluxe image.
The simple gothic logotype lends prominence to the dynamic feature of the Xi symbol mark. The logotype and its proportions and spacing should not be arbitrarily altered.
