Please fix uranium ore color as well. They should be a tad bit yellowish compared to current color. Also if possible, fix the nuclear glow as well as they should glow blue inside reactor.

I've done some research and yes, you're right. Uranium is usually yellowish.

Although, they may be a problem with that. I've never used any mod that adds new resources to the game but I strongly suspect that one of them adds sulphur ore. If I change uranium to yellow, they would be two very similar ores and I very much wouldn't like to interfere with other mods. There is no such problem with iron and copper because they more or less switch colors with each other.

I am not saying that I definitely won't change color of uranium. I just wanted you to know what kind of problems this may create.
I have think about this some more.

I know for sure that I won't change glow of nuclear reactor. I like this idea but this mod is about ores.
You may want to create suggestion at forum about it.

Ok, I found 3 mods that are adding sulphur to the game. Or seems like they won't be a problem if I change uranium to be yellow-green. It should remain distinguishable from purely yellow sulphur.

I also found that zinc ore from mod "Bob's ores" looks almost like my copper. Oh well ¯\(ツ)/ ¯

Done!
Perhaps color of uranium is still a little too green but at least it shouldn't collide with anything else.

OK, you've won. ;) I made a mod which changes the nuclear glow color. https://mods.factorio.com/mod/RealisticReactorGlow
