Honestly I didn't look very closely at the screenshots and assumed it was a color filter like most games these days, but just changing the HUD is actually probably perfect, so kudos to CDPR. I haven't played enough Cyberpunk to know if color comes up in any other gameplay elements or anything, but other than the HUD, something being color coded in some way is usually the only time it's an issue, and having something like a shape tied to whatever you're labeling like you described is good enough.

I think just the standard "item glow" or whatever you want to call it is good enough for highlighting objects, there might be someone out there who might struggle with the color you pick against some backgrounds, but even having 3 distinct colors would cover anyone I would think.

The problem with the filter some games have implemented is it's fixing the few elements that could be difficult for colorblind players by trying to fix their colorblindness instead of just fixing those few things. You and I might look at an object and see a different hue but it's still what both of us are used to seeing and trying to shift the entire color palette is going to make everything look way off, even if now I can tell the friendly and enemy healthbars apart easier.
