DO THE NEW LEAVES ON A MONKEY PUZZLE HAVE A BROWNISH ORANGE COLOUR

No, they don't, should be green. Should be in well drained soil, but if planted less than a year, specially in a pot, should be kept well watered with drainage hole in the pot.

I HAVE HAD IT IN A POT A YEAR AND THERE IS A LOT OF NEW GROWTH AND I WATER IT EVERY DAY IT LOOKS HEALTHY BUT I HAVE JUST NOTICED THE LAST WEEK JUST THE 2INS ARE A DIFFERANT COLOUR

Ah, probably needs a larger pot then, and when you do it, check the compost and root system carefully for any invaders.
