This study deals with the regulation of colour simultaneous contrast. We have proceeded to the measurement of the regulation effect of a scene in a situation where a strong induction generated by a large peripheral field is counterbalanced by a complex colour surround in the neighbouring. Results show that every neighbouring scene considerably reduces the chromatic contrast induced by the large peripheral colour field. Although every neighbouring scene has the same average chromatic content, the resulting colour appearance of the target seems to differ between scenes, and this may be ascribed to the spatio-chromatic organisation of the scene.
