Color Theory





				Theory of Color There are two ways to create a color: addition and subtraction. Neon lights are mainly additive--they create light by gasseous discharge of neon gas or mercury vapor, most of the time in conjunction with a phosphor layer. This allows for an almost limitless possibility of colors. Subtraction is also used to obtain very saturated, deep hues. This is done two ways: by a filter layer of a colored ceramic between the glass and phosphor layer, or by using colored glass tubing. By using both additive and subtractive colors, we can create just about any color you desire!
