灰色布 meaning in English

gray cloth

Then no sooner was the house empty than it grew dark : the footlights went out ; the chandelier was turned down ; long strips of gray canvas slipped from the stage boxes and swathed the gilt ornamentation of the galleries , and the house , lately so full of heat and noise , lapsed suddenly into a heavy sleep , while a musty , dusty odor began to pervade it
随后，观众还未走完，大厅内就暗下来，成排脚灯熄灭了，大吊灯的光线变暗了，长长的灰色布罩从舞台两侧的包厢上落下来，盖住了楼厅的金色装饰。那样炎热人声鼎沸的大厅，顿时仿佛沉睡了，发出一股霉味和尘土的气味。
