Question A dark shade on top of video.

I am doing a simple video in unity 3d, but the video is not in the correct color, it has a dark brownish shade on top of it. The video original color should be just pure white and aquamarine. I am using a plane to place the video. How can I fix this problem?

 

try using some unlit material (plane seems to have default-material assigned, might have some non-white tint color too)
