Black Widow Paint is a paint with four special slick agents that seek to be competitive with other projection screen manufactures. History of DIY painted screens{{Main|Projection screen}}Projection screens are primarily white or gray. A white screen is better balanced and more accurate {{clarification|date=October 2018}} when it is close to D65 (the international standard illumination conditions). A gray screen is more accurate when it is closer to neutral, based on parameters such as color balance (L*ab and xyY values), spectral curve and color temperature. The most popular{{citation needed|date=October 2018|reason=Unverified claim}} way to improve a simple neutral gray color, up until now, has been by the use of mica (pearlescent) and poly coatings. The problem with mica is it causes a color shift. To improve on a well-balanced neutral gray, without introducing color shifting, non-interference pigments are used. It was discovered that by adding aluminum-based paint (which is water-based, primarily made out of aluminum with no other colorants), a gray color was created. This paint has been used over the years{{citation needed|date=October 2018|reason=Used by who, for how long?}} as a 'silver' substitute, since the aluminum's bright and reflective properties are conducive to applications such as manufacturing mirrors.
