A port of the SLIB color library. For documentation see:
;;; construct some colors in various color spaces ;;; and measure their distance from the D65 white-point (use color) (let ((rgb-red (make-color 'sRGB '(255 0 0))) (lab-yellow (make-color 'L*a*b* '( 76 7 130))) (luv-blue (make-color 'L*u*v* '( 32 -9 -132)))) (print "rgb-red's distance from the D65 whitepoint is " (CIE:DE* rgb-red D65 D65)) (print "lab-yellow's distance from the D65 whitepoint is " (CIE:DE* lab-yellow D65 D65)) (print "luv-blue's distance from the D65 whitepoint is " (CIE:DE* luv-blue D65 D65)) (print "D65's distance from the D65 whitepoint is " (CIE:DE* D65 D65 D65)))
