L*a*b*
color space
The L*a*b color space is one of the
most widely used and useful of the color models. L*a*b was developed
by CIE in 1976 as a refinement of the XYZ color space. As XYZ, L*a*b
is also device independent and represents every color through three
components.
The L value represents luminance and
ranges from 0 for black to 100 for white in uniform steps.
The a and b values are represented
as +a/-a for red/green and +b/-b for blue/yellow.
One
of the main application area of the L*a*b color space is in color
faxing and JPEG compression.
