Exporting image as PNG turns white color to gray

[Hunky]

I am having a veeery strange issue. When I try to export my graphics assets (PNG), the white color turns darker and closer to a gray color than pure white. Has anyone experienced this before?

 

It is pretty clear to see if you compare (or color pick) the result in the export preview with the original to the right

Welcome to the Serif Affinity forums.

Both the original and the export preview appear grayish to me, though the preview is grayer than the original.

What color space does your document use? What color profile?

Thank you!

Happy to be here, and happy to discover it is as active as it is.

Here are my Document Setup settings. Do they affect how Affinity exports images?

Those should be OK.

Can you share your original .afphoto or .afdesign file?

For the record, I'm aware there's a gradient overlay effect applied, however, I wouldn't expect it to darken the exported result as much as it does. The difference between the asset on the artboard and the asset that is exported is unreasonably large.

The gradient overlay effect is buggy: when the gradient stops have reduced opacity, the opacity of the entire object is affected.
