Why image color matching is very important

Heinz Groß sent me a good test image for testing whether an application does color matching correctly. Click on this picture to open the test image and see how it looks like:

There are two possibilies how this picture looks like:

The picture has a color circle and inside the names of the colors in German. Where you read ROT, you should see red. And where you read BLAU, you should see blue. So the left picture is wrong and the right one is correct in colors.

How it works? Well, this image has a very special ICC Profile which switches the color channels for red and blue. Applications which use the profile will show the correct picture and others will show the raw pixels.
