| achromatic |
Light without color. The quantity of light is the only attribute associated with achromatic light. In physical terms this is the intensity or luminance or in the psychological sense it is the perceived intensity in which case the term brightness is used. In the YIQ or YUV representations, this is the Y component. In the HSV representations, it is the V (value) component. In the HSL representations, it is the L (lightness or intensity) component.
