| Abstract: | The observance of color within the photochromatic interval has been shown to be possible. By pre-stimulating the subjects in a dark-adapted state, using Kodak Wratten Color Filters No. 70 (red), No. 73 (yellow) or No. 74 (green), and test-stimulating 30 sec. later with yellow, green, or blue filters at levels of intensity between the specific and absolute thresholds for these filters, it was found that they observed a blue or violet color. |
