Pixels Change Color

The pixel sprites i imported into unity change color for some reason so if i put brown next to yellow the yellow will turn dark. Its stupid and i dont get why that happens i tryed i unity 4.5 and 4.3.1 2D mode but the some pixels just change color.

i am not sure what you mean, but anti-aliasing and lighting can both effect your colors on individual pixels.

The pixels change color for some reason so if i put brown by yellow sometimes the yellow will turn dark or the other way around when imported into unity
