This image doesn’t contain a single red pixel. You perceive red because of your brain perception (color theory)

If I see the entire picture, the center right and bottom left panels look red(ish) to me, along with the strawberries.
But if I scroll the portion of the picture that has the strawberries in it up so that I only see the crust, then those two go back to being a shade of grey.
