Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
As a general rule it's best to go for a contrast of 50% between different interactions/design elements to ensure they are clearly visible to the viewer. So if you're wanting a grey to contrast with #000000, go for #808080 or lighter.
I don't remember where I read the 50% rule, possibly somewhere in Google's app design guidelines. Anyway, I've been applying it to my designs for years and I've not had any problems with legibility since.
