What 'pure white' really means
Amazon's main image must sit on a pure white background defined as RGB 255,255,255. Backgrounds that are cream, light grey, or faintly tinted will fail even though they look white.
Why Amazon enforces it
A uniform pure-white background makes products look consistent across search results. The safest path is to remove your original background entirely and set a true 255,255,255 white.
