In summary, it is difficult to find a printed version of the CIE xy chromaticity diagram that accurately represents colors and hues. The best option may be to purchase a Pantone reference color swatch, but this can be expensive. Alternatively, a digital version can be printed by a high-quality printer, but it would need to be calibrated first.

Where may an individual purchase a printed copy of the CIE xy chromaticity diagram, showing (reasonably) true colors and hues? Preferably, I would like to have a copy that shows some of the wavelengths of the monochromatic colors around the periphery of the diagram (except, of course, for the "purples" on the line between the shortest and longest wavelengths.)

Thanks,

Bob65

You won't get a printed version which shows the spectral colours with any accuracy because colour printing is really not up to it. You can buy a swatch of pantone reference colours (at great expense), which afaik, is the most accurate printed representation of colours. What you get from a good quality colour display gives the best you can expect but the spectral colours are, of course, outside the gamut of the primaries. For spectral colours, you need a good white source and a prism or grating.
You can do the googling as well as I can; I spent a short while looking and found this link for use with a colour monitor. Of course, you would need to calibrate the monitor first, with a Spyder or similar. The Colour checker chart can also be bought, I believe.

Failing those ideas, you could get a digital copy (with the annotations you want) of the best CIE chart you can find on the net and take it to a good photographic printer. It would not need to cost more than a few £.
 

FAQ: Obtaining copy of CIE xy chromaticity diagram

1. What is a CIE xy chromaticity diagram?

A CIE xy chromaticity diagram is a graph that visually represents the range of colors that can be perceived by the human eye. It is used to map out the chromaticity of colors, which is the quality of color that distinguishes it from white or gray.

2. Why is it important to obtain a copy of a CIE xy chromaticity diagram?

Obtaining a copy of a CIE xy chromaticity diagram is important for many reasons. It can be used in color matching and color reproduction, as well as in the development of color standards and color spaces. It is also a useful tool in the study of color perception and the relationship between color and light.

3. How is a CIE xy chromaticity diagram created?

A CIE xy chromaticity diagram is created by plotting the chromaticity coordinates of colors on a graph, using the x and y values from the CIE 1931 color space. These coordinates are determined by measuring the spectral power distribution of a color and using mathematical calculations to convert it into a chromaticity value.

4. Where can I obtain a copy of a CIE xy chromaticity diagram?

A copy of a CIE xy chromaticity diagram can be obtained from various sources, such as scientific journals, textbooks, or online resources. It can also be created using software programs that allow for the plotting of chromaticity coordinates.

5. How can a CIE xy chromaticity diagram be used in research?

A CIE xy chromaticity diagram can be used in research to study the color properties of different objects, light sources, or materials. It can also be used to analyze color perception and color preferences in different populations. Additionally, it can aid in the development of new color technologies and standards.
