第2个的结果有些奇怪,既然是以Lab取值的点,为什么会落在LAB色彩空间外面?
----------------------------------------------------1-------------------------------------------------------

-------------------------------------------------------2-------------------------------------------------------cols = {LABColor[0.5, 0.2, 0.4], LABColor[0.8, 0.3, 0.4],LABColor[0.3, -0.2, -0.4],
LABColor[0.2, 0.5, 0.7], LABColor[0.9, -0.5, -0.6], LABColor[0.6, -0.7,0.4]};
sph = DiscretizeRegion[Sphere[{1/2, 0, 0},1/2], MaxCellMeasure -> {1 -> 0.05}];
Show[ChromaticityPlot3D[cols, "LAB",PlotStyle -> AbsolutePointSize[6]],
Graphics3D[With[{pts= MeshCoordinates[sph]},
GraphicsComplex[pts,{Directive[Opacity[0.8], EdgeForm[]],
MeshCells[sph, 2]},
VertexColors -> (LABColor @@@ pts)]]],
BoxRatios -> Automatic]
