Why 'looks white' isn't enough
A background that looks white on screen is often slightly off-white, grey, or cream due to lighting. Amazon's system reads exact pixel values, so even a faint tint or a soft shadow touching the edges can fail.
How to fix a non-white background
Remove the original background and replace it with pure white (RGB 255,255,255), keep clean edges, and make sure no shadow bleeds to the image border.
Frequently asked questions
What RGB value does Amazon need?
Exactly 255,255,255 — pure white.
Why does my image fail even though it looks white?
Lighting or compression can leave the background slightly tinted, or a shadow may touch the edge.
Will a white background guarantee approval?
No — it's one requirement among several (size, product fill, no text).
