A color-matching apparatus for visual on-light evaluation of flexible copies includes a support for at least one copy having a supporting surface being concave as viewed by an observer. An areally radiating illumination configuration emits light of a defined type onto copies and generates a defined intensity of illumination in the supporting surface. The illumination configuration has a radiating surface being substantially convex, as viewed by the observer.
