Photos Markup eyedropper color changes after saving

When using markup in photos, and using the eye dropper to match a color, it appears an exact match while drawing. But when you’re finished and save it, the color changes to a slight variation. I’ve never had this issue up until recently! I couldn’t figure out how to attach a screen recording so here’s the vid on YouTube demonstrating what I mean. https://youtu.be/2wbrAeNIeWw I draw an X in the middle of the pic, which appears to be an exact color match until I save it and you can see the color changes slightly.
