Publication asking for RGB files

[kellyjonesphoto]

All of my editing is done in sRGB, however I have a request for jpeg images for a national publication and that they be in RGB format. I am assuming this would be Adobe RGB? When I export from LR as Adobe RGB color profile and open the image in PS it still shows sRGB in the settings. Can someone clarify this for me?

No, they literally do mean RGB.

Stick to sRGB.
