Lighting design of Copenhagen DDT building (three)

Color changes through the entire staircase, and repeated, with 7 numbers as a rule. 7 colors are purple, purple blue, blue, green, yellow, brown, and red, and there are 77 units. White as the main color and other colors at the same time. Each color changes with a 7 unit step as a set of rolling up. Each unit lasts 20 seconds, so a color from the first unit to reach the seventy-seventh unit is a process of 20 seconds, which is about 25 minutes. However, it will take 3 hours and 20 minutes to turn the entire staircase into a color, and it takes about 28 hours to rotate all the 7 colors. From the technical point of view, this kind of program is based on an additive color mixing phenomenon. Because light is made up of red, green, and blue three primary colors, and it becomes white when it is uniformly superimposed. Scott took advantage of this phenomenon, the red, green, blue three kinds of light source using the computer to control the spectrum of a set of light "Overture", and the color of each module and the rhythm of the rhythm of the rhythm of the program. In addition, the "Overture" in each note and rhythm are very harmonious, the layout of the building color into a color of music.
