Protanopes and deuteranopes do not accept the classical dichromatic matches when field size extends to 8° visual angle. Their unique matches of spectral yellow to a mixture of red and green are then mediated by the photoreceptors of small-field dichromacy interacting with a photoreceptor with the spectral sensitivity of rhodopsin. Our data suggest that large-field trichromacy is a general feature of protanopia and deuteranopia.

  26. The suggestion that spatial and temporal border transients could explain our data was first made by D. I. A. MacLeod at the annual meeting of A.R.V.O. in 1976.
  27. We attempted to evaluate the effects of border transients in two additional ways. We constructed an 8° field stop with a 2° black bar. The 2° bar prevents an observer from making direct comparisons across the test-field border. With this test field, discrimination deteriorated. However, protanopes SY and CB and deuteranopes DK and MM continued to reject the neutral point match of 494 nm to a mixture of 450 and 650 nm. Their red-green matches for wavelengths 570, 589, and 610 nm widened, similar to those for one-thousand-fold reduction in field luminance (Fig. 7). Our second approach was to defocus the field so that the border was invisible. Again, discrimination was reduced, but not to the same degree as with the 2° bar separating the test and mixture fields.
