I'm not sure I see why. I've never seen unwanted colors testing my patch,
even when I deliberately lined up two clashing colors halfway between pixel
boundries:

// +w160 +h120 +am1 +r8 +a0.0
global_settings { assumed_gamma 1.0 }
camera { orthographic right 4/3*x up y direction z }
plane { -z, -1 pigment { checker rgb <0, 1, 1>, rgb <1, 0, 1> scale 1/4
translate 1/240 } finish { ambient 1 } }

But I'm curious to hear what you have in mind.
