Many ALR projection screens on the market today play with color balance in order to keep as much light as possible away from the eyes of the viewer. This creates an image that doesn’t look quite right, although it’s hard to say why, at least until you do a side-by-side comparison with a screen that is reflecting colors accurately. Then you notice how blue the typical ALR screen image is.
People depend on correct colors not only to visualize, but also to understand. Our ability to see in color allows us to sense emotion or to see health on the skin of others. Getting the wrong color signal might lead us to misread an enemy’s intentions or to be exposed to unwanted illness. Color balance can even mean the difference between right or wrong diagnoses using a microscope in the lab.
In nature, showing off the correct color warns possible predators that a South American arrow poison frog isn’t a good idea for dinner. Being the right color to blend in with tree branches gets the mantis its insect meals. And if a male peacock’s tail feathers are bright and colorful, females know he’s healthy.
Draper was the first screen manufacturer to make ALR screens that are certified by the Imaging Science Foundation (ISF) for color accuracy. All of its ALR screens have this certification, which means they have no impact on the image color.
When used in conjunction with an ISF-certified (or correctly calibrated) projector, the colors you see appear as they are meant to be, so you can have confidence that no matter how critical the situation, there won’t be any mistakes due to bad color balance.
