Inspired by the story of Newton discovering color light in the history the project is the key visual and series poster design for 1st Academic and Cultural Festival for Graduate Students, ECNU. Parallel lines and strong colors have been used to express chromatic ray, symbolizing multidimensional collision of ideas, interdisciplinary academic exchanges, and a vibrant cultural community. The "Ray" here represents the "Ray of academic", "Ray of ideological", and "Ray of equal", which is a tribute to the scientific exploration spirit of independent thinking and the pursuit of truth.
