Once all of the sudden I come a cross this issue, I tried few fixes that found over the internet search. Unfortunately non work until I re-install the NX.

Hi, I had the same problem, then I rendered it in the Studio, finished it and then the true colors of the parts showed up.

Edit: Found out I just basically changed the style of rendering (right-click on mouse) to studio rendering

it's working to see the part/component color, somehow in Studio mode. but not resolve the issue fully.

I followed your step, first I import the assemble part, which shown black

Then I just click "Studio Task" to render wow yes colors appeared and finished task.

Simply this, turning the "Style" mode to "Studio" style mode

However, all the assemble part/component color need to correctly shown in "Shaded with Edges", style mode also.

Any way this is better knowing, at least I can see part clearly in Studio style mode when assembling & adding constrain.

Have you try resetting NX to initial state, that describe in this post?

Yes, I have followed the NX resetting procedure that described here. I can see almost every setting of the NX now in initial state. Although , I have no luck solving this assembly part load in black color issue. Seems, black color now hard coded to loading assemble parts.

In my NX when I try to load the new part via assembly all the parts are showing as pully black color irrespective of the individual part color.

How & which setting make this issue? and how do I change this all assemble part shown as pitch black color?

This is caused mainly because Graphic Drivers incompatibilities or errors, I solved this problem once downgrading my drivers (NVIDIA RTX 2060) to old versions.

You are absolutely correct & Thank you...!,

I just re-installed the my NVIDIA GTX driver way over 1year old one just to check. Yes now the assemble parts shown in correct color and black color issue gone.

I recheck my old same assembly, after old driver installed and now working fine.
