Why does my white background look slightly gray?

This can happen if a gradient was selected instead of solid white, if the image was saved as JPEG (compression alters pixel values), or if your monitor brightness and calibration make pure white appear off-white on screen.

What is the exact white color code required by Amazon?

Amazon requires pure white backgrounds at RGB(255, 255, 255), which is hex #FFFFFF. Any value below this will appear as off-white and may trigger listing rejection during their automated review.

Does JPEG format affect white background purity?

Yes. JPEG is a lossy format that approximates pixel values during compression. A #FFFFFF white pixel might be saved as #FEFEFE or #FCFCFC. Always use PNG format when exact white backgrounds are required.

How do I check if my background is truly pure white?

Open the image in any editor (Photoshop, GIMP, Preview) and use the eyedropper tool on the background. The values should read exactly R:255, G:255, B:255 or hex #FFFFFF.

Which marketplaces require pure white backgrounds?

Amazon, eBay, Etsy (for certain categories), Walmart Marketplace, and Google Shopping all prefer or require pure white backgrounds. Amazon is the strictest, rejecting listings with off-white backgrounds.

Can I convert an off-white background to pure white?

The easiest approach is to re-process the image in Backgroundless with the solid white preset selected and download as PNG. This guarantees exact #FFFFFF rather than trying to adjust an existing off-white image.

The Problem

After adding a white background, the result is not pure white (#FFFFFF). The background appears slightly gray or off-white, which causes rejection on marketplaces like Amazon that require exact pure white backgrounds for product listings.

Common Causes

1.Gradient or pattern background selected instead of solid pure white

2.Image saved as JPEG which introduces compression artifacts altering the white value

3.Monitor color calibration makes pure white appear off-white on screen

Step-by-Step Solutions

Select the pure white preset in Change Background tab

Go to the Change Background tab and select the white color preset from the solid colors section. This sets the background to exact #FFFFFF, which is pure white at RGB(255, 255, 255).

Ensure you are using solid white, not a gradient

Check that the background type is set to Solid Color, not Gradient or Pattern. White gradients will have non-white areas that fail marketplace validation. The solid white option provides uniform pure white.

Download as PNG for exact color preservation

Use PNG format when downloading your image. PNG is lossless and preserves the exact #FFFFFF color value. JPEG compression can shift white pixels to slightly off-white values (e.g., 252, 253, 254).

Verify in an image editor that background reads RGB(255,255,255)

Open the downloaded image in any image editor and use the color picker or eyedropper tool on the background area. Confirm it reads R:255, G:255, B:255. This is the exact value marketplaces require.

Prevention Tips

Always use PNG format for marketplace submissions requiring exact white backgrounds

Double-check the background type is Solid Color before downloading

Test your images with marketplace listing tools before uploading to catch color issues early
