monochromatic

However, if you want to wear a print, choose a print that's low in contrast and monochromatic in color..然而，假如你实在想穿喷绘衣服，那就选择一件单色、低对比度的。

This hologram, if later illuminated with the same wavelength of laser light, reproduced a 3D (but monochromatic) image of the object..这幅全息图，如果用（与拍摄时）相同波长的激光照明，会再现出物体的3D图象（不过是单色的）。

monochromatic light,单色光

monochromatic radiation,单色辐射
