Color Blending During Render

I am trying to render this pattern I imported into the editor from a PNG Image. The pattern has just two colors with an angled border between them. However, when I render, the colors become blended along the border, and some of the pixels are even dropped to 0.

I’ve tried to turn off Anti-Aliasing, which helps, but doesn’t eliminate the problem entirely. The output should just be the two colors.

Try changing the texture filter to Nearest. The image will be sharper and less blurry.
