Exporting changes color

You have posted your problem in the wrong community. Looking at your images, you are working with Lightroom, not Lightroom Classic.

Correct community: https://community.adobe.com/t5/lightroom/bd-p/lightroom?page=1&sort=latest_replies&filter=unresolved

So people don't have to download the image you have attached to your post please Edit your post to remove the Attached screen shot and Include it in the body of the text of your post.

You do that by Clicking the "More..." link at the bottom of your post, Selecting "Edit Message" and then use the "Insert Photos" icon in the tool bar at the top of the Post/Reply/Edit dialog box like this.


Thank you.

Please include the screen captures in your message by clicking on the "Insert Photos" icon. Do not include them as attachments.

Difference in color could be caused by many issues. Did you choose the sRGB color space when you exported? What application outside of Lightroom are you using to look at the exported photos? Is your monitor properly calibrated?
