Roscolux 20 x 24 Inch Sheet 321 Soft Golden Amber

An amber with some green content. A good sunlight transition color that shows the progression of the sun from white or yellow to amber later in the day. (Transmission = 39%).

Filters create color by subtracting certain wavelengths of color. Thus, a red filter absorbs blue and green, allowing only the red wavelengths to pass. The process is subtractive, not additive, so the light source must emit a full spectrum.
