Defining Pure Color and Monochromatic Stimuli The term Pure Color, particularly within the domains of perception and psychophysics, refers specifically to the sensation elicited by light that is composed of a single, narrow band of the electromagnetic spectrum. This physical characteristic is known as monochromatic light. Unlike the vast majority of colors encountered in the […]
Introduction to Dominant Wavelength The concept of the dominant wavelength serves as a cornerstone in the field of colorimetry and visual science, providing a quantitative metric used to characterize the hue of a perceived color. Fundamentally, the dominant wavelength is defined as the single monochromatic light stimulus that, when additively mixed with a specified reference […]
Introduction to Extraspectral Hue The concept of an extraspectral hue refers to any perceived color that cannot be generated by a single, narrow band of light wavelength within the visible spectrum. Unlike pure spectral colors, which correspond directly to specific electromagnetic frequencies, extraspectral hues are inherently composite, resulting from the simultaneous stimulation of the retina […]
Introduction to the Spectral Scale The Spectral Scale represents the organized continuum of colors derived from the electromagnetic spectrum, specifically focusing on the portion visible to the human eye. Fundamentally, this scale is a systematic mapping of light wavelengths to their corresponding perceived colors. While the concept appears straightforward—a simple arrangement of hues—it underpins vast […]
