Neonates' cone receptors, which are responsible for color vision, are not fully developed at birth, so they cannot distinguish between all colors. However, studies have shown that they are able to differentiate between red and white, which may be due to the fact that red light is longer in wavelength and easier for their immature cones to detect.
