Colors Muted On Export

I am exporting a slice from figma to upload as an email. I am exporting my slice as a PNG but the colors keep getting muted (not as high rest). I’ve tried exporting from 1x-4x with no changes in results, and tried exporting both as PNG and JPG. See screenshot below, the left image is my export from Figma and the right is how the image is displaying in my Figma file.

How do I export high-res images? Thanks.

This might happen if your colorspace in the Figma app is set to Unmanaged. Try changing to sRGB to see if the colors match:
