Eldaria/Gyson, I'm also colorblind, and have posted about the exact same type of issue in the "Beta UI Wishlist" thread - glad to see I'm not alone on this request either. Here's what I've requested in that thread (as I have trouble distinguishing between the yellow and orange icons):
2) The "chest" action icon color for containers that are "not owned" but not yet opened should be changed from yellow to white
This would assist colorblind players, as the "chest/door/hand" action icons for all containers/doors/items would be orange if "owned," and white if "not owned," with the label "[Empty]" added but the icon color unchanged if a container is empty
Like you say, simply changing an assigned icon color or maybe shape would be extremely easy compared to everything else that's already been (and is still being) changed. I just hope the devs realize this is worth fixing.
