AdobeRGB & sRGB test charts

This webpage links to several pages of test charts and images.

The following pages can be used to test whether a wide-gamut display is correctly set-up and whether the display software is correctly applying image colour profiles.

Page 1 - The charts of coloured squares on Page 1 test the capability of a system to display colours at the edges of sRGB and AdobeRGB colour spaces.
Page 2 - The coloured ring charts on Page 2 also test the capability of a system to display colours at the edges of sRGB and AdobeRGB colour spaces.
Page 3 - The Passport Colour Checker photographs on Page 3 test the capability of a system to correctly render images with and without sRGB and AdobeRGB colour profile tags and the corresponding embedded ICC profiles.
Page 4 - The Passport Colour Checker photographs on Page 4 can be used to check whether sRGB images with and without embedded sRGB ICC profile data are rendered identically by a web-browser on a wide-gamut monitor.

Once system set-up has been checked, using the four pages above, the following pages can be used to see the difference between images rendered in AdobeRGB and sRGB colour spaces on wide-gamut displays. There are 3 images on each page. The first image on each page was created in AdobeRGB space and contains some saturated colours that are outside sRGB colour space. The second image on each page was created by correctly converting the first image from AdobeRGB colour space into sRGB using relative colorimetric intent. Most of the image will appear unchanged, but any colours that are outside sRGB space will have been adjusted (shifted) so they lie within sRGB colour space. The third image on each page was created by assigning an sRGB colour profile to the AdobeRGB image data in the first image. This image will be rendered differently. It will appear duller than the other two. Unfortunately images created in this way are sometimes used to (incorrectly) illustrate how much more colourful the same image is in AdobeRGB colour space compared to sRGB.

Page 5 - The squared charts on Page 5 demonstrate the extra colours available when using a wide-gamut display.
Page 6 - The ring charts on Page 6 can be used to see the extra colours available when using a wide-gamut display.
Page 7 - The Passport Colour Checker images on Page 7 can be used to see the difference in how a colourful photograph is rendered on a wide-gamut monitor in AdobeRGB versus sRGB colour spaces.
Page 8 - The imagess of Oban Harbour on Page 8 can be used to see the difference in how a colourful photograph is rendered on a wide-gamut monitor in AdobeRGB versus sRGB colour spaces.
Page 9 - The images of a Poppy on Page 9 can be used to see the difference in how a colourful photograph is rendered on a wide-gamut monitor in AdobeRGB versus sRGB colour spaces.
Page 10 - The images of a real rainbow spectrum on Page 10 can be used to see the difference in how a colourful image is rendered on a wide-gamut monitor in sRGB, AdobeRGB and ProPhotoRGB colour spaces.
