Red Bi- powder has the unique property of being a black powder as well as a colored powder. When dusted on light-colored surfaces, the powder appears black. However, when it is dusted on a dark-colored surface, appears bright red for easy photography.

You can use the same Zephyr® fiberglass brush and Red Bi- powder for a majority of your dusting requirements at crime scenes. The greatest advantage of using Red Bi- powder is that the lifted prints will be black when placed on a white backing card. This eliminates the bother of comparing latent prints with light-coloured ridges on a black background against rolled prints with black ridges on a white background. It also means that only white backing cards will be needed. There is no need for black backing cards with Red Bi- powder.
