Therefore, the custom shade of grey I think I should be using would be #AFAFAF. (Since both of the afore-mentioned "official" shades of grey use the same Edge Color, I do not need to create a new such shade.)
Now that I have the RGB hexadecimal value to use for the desired shade of grey, how do I use this info in my LDraw models, please?
Just set the color number to 0x2AFAFAF. LDraw color numbers in the range 0x2000000 to 0x2FFFFFF are opaque direct RGB colors of the form 0x2RRGGBB. (For reference, 0x3RRGGBB color numbers are transparent direct RGB colors.) See here:
