Abstract

By stabilizing the image of a green adapting field on the retina and surrounding it with a yellow annulus whose outer boundary is unstabilized on the retina, we were able to use filling-in to change the apparent color of the green disk to the color of the annulus. By reversing the colors of the annulus and field we changed the filled-in color to green. This color change only occurs with retinal image stabilization. Using this method, we examined whether the apparent color of the adapting field influences the CFF of a superimposed test spot. The test spot consisted of counterphase-flickering tritan metamers at various contrasts, which generated time-varying signals exclusively in the short-wavelength cone pathway. We found that for our conditions, CFF depends on the perceived color of the adapting field independent of the spectral distribution of its retinal image. These results indicate that CFF can be influenced by a chromatically coded neural site that is itself influenced by the filling-in process.
