DescriptionCIE1931xyY PlanckianLocus-fr.svg	English: CIE 1931 xy color space diagram. Drawn (or rather programmatically generated) from scratch, but the visual design is based on File:CIExy1931.png by w:User:PAR. Major differences: Colors outside the sRGB triangle are clipped toward the sRGB white point, so they have more accurate hues. The original image (and most other images of this type) clips each sRGB channel independently to zero, which among other things leads to the whole top of the diagram being colored #00FF00 (sRGB primary green) when it should be more of a cyan. Luminance inside the triangle was reduced somewhat. Maximum luminance (the infinity norm) creates a three-pointed star artifact (the lines are #FFFF00, #FF00FF and #00FFFF). Constant luminance (1-norm) looks rather dull. An intermediate p-norm makes nice-looking results without the star. This background image uses p=5 (if I remember right). Gone with the star is the clearly defined white of the D65 white point, which is also an sRGB artifact. Blurring of the sRGB triangle edges to hide artifacts there. This means the colors near the boundary are slightly less accurate (not maximally saturated). I prefer this to the line artifacts, but it's an issue that could be debated. Labels at uniform 20nm intervals; left out 380nm and 700nm because the locus doesn't really stop there or anywhere, it just fades into nothingness; no grid on the x + y > 1 region; random tweaks, yada yada yada.

SVG development InfoField	The source code of this SVG is invalid due to 12 errors.  This W3C-invalid diagram was created with Inkscape.   This diagram uses embedded text that can be easily translated using a text editor. This SVG diagram contains embedded raster graphics.[1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics. Note: This template is only supposed to be used if the SVG file mixes vector and raster graphics. If the SVG file only contains raster graphics {{FakeSVG}} is supposed to be used. See also {{TopoSVG}}. This diagram is a retouched picture, which means that it has been digitally altered from its original version. Modifications: Ajout du lieu planckien.
