That's not accurate. The human eye uses primarily green to detect resolution. Red and blue are used for color.<p>I wish I could find it, but there was an online example, where someone took a picture, divided it into the three channels, then pixelated (mosaic) one channel at a time and recombined it.<p>When he did green you saw it right away. With red it took some pixelation before you could see it. And with blue it took a LOT of pixelation before you noticed anything.
