If I cut back my conifers will I get green growth at the top or will it stay brown wood

Most conifer don't green up if you cut back beyond the green. Leylandii don't and that's what a lot of conifer hedges are
If you cut the top out that will green back up. If you cut back at the sides in many cases it won't recover and you will be left with a large area of brown stem.
I had a line of about 15 Leylandii when I moved into my house - very tall. I had them trimmed to about 14ft. They all died
I have 2 leylandii in the garden as a windbreak. They are about 15 ft high and tops get cut every few years. No idea what the tops look like - they are high enough not to be seen! Dpends very much on how high you are going to cut them.
