For example, would 50% gray correspond to a color which is visually 50% between black and white? The CIE lightness (L*) has that property. L=0 is black, L=100 is the media white. L=50 is exactly a mid grey. It could be used by itself or as part of the CIE Lab or LCH color spaces (C and H are chroma and hue angle) - to give warm or cool greys for example. -- Chris Lilley Technical Director, Interaction Domain W3C Graphics Activity Lead, Fonts Activity Lead Co-Chair, W3C Hypertext CG Member, CSS, WebFonts, SVG Working Groups
