本项目为一家东京油漆公司的总部大楼，在改造前建筑是一座典型的铅笔楼，仅满足疏散的法律要求。如今，独特的“垂直彩虹”出现在立面上，代表着这家公司已经成长为一家全球性的公司。
The former headquarters building was a stereotypical pencil building that merely met the legal requirement for evacuation. Now that it has grown into a global company, a “vertical rainbow” appeared on the facade to express its identity as a paint company offering an infinite variety of colors.

在本项目中，设计团队将一种新开发的室内涂料创新地运用于室外玻璃，在钢化夹层玻璃上实现了色彩渐变的效果。为了使立面看起来只由彩色玻璃组成，玻璃仅由顶部和底部两侧的水平框架支撑，这些框架比露台的宽度更宽，并以极简主义的手法进行了细部处理。
Using a newly developed in-house paint for outdoor glass, we applied a gradient coating to tempered laminated glass. In order to make the façade appear to be composed only of colorful glass, the glass is supported only by horizontal frames on the top and bottom two sides, which are wider than the width of the terrace, in a minimalist detail.

直射进室内的日光通过彩色玻璃转换成彩色光线，在露台地板和相邻建筑的外墙上创造出美丽的阴影。
Direct daylight is converted into colorful light through the colored glass, creating beautiful shadows on the terrace floor and on the exterior walls of the adjacent buildings.

而多云的天气里，玻璃表面将天空反射地更加清晰，变化的云和颜色融合在一起，创造出美丽的立面效果，如同数字艺术一般。
When it is cloudy, when the sky is more easily reflected, the changing clouds and colors blend together to create a beautiful facade, like digital art.

从办公室透过露台向外看，城市的景色变身为一幅彩色的风景照片，各种各样的城市景观感觉就像一件件超现实主义的艺术品。
The view of the city from the office through the terrace is like a landscape photograph with added layers of color. The miscellaneous cityscape feels like an unrealistic artwork.

夜晚，在灯光的照射下，彩色的玻璃透出柔和的光芒，在建筑林立的街道上形成一道“夜的彩虹”。
At night, the glass illuminated by the lights emits soft colors, creating a “night rainbow” on the street lined with buildings.
