This is a great image that was rendered synthetically using a ray tracing program Bruce Lindbloom wrote himself. It is a good illustration of the dangers of linear gamma image storage as well as a clear & clean image for testing profiles while still retaining the appearance of a real-world scene.
Testing profiles using only colored patches is not terribly effective as the eye cannot judge colors in such an absolute form. Continuous tone images containing memory colors (flesh tones, plants, sky, some foods) are better as the eye picks up variations much more effectively.
