Pressure Treated Fencing Green Tinge

I am looking for decorative fence panels for a decking area and almost everything i see has a green tinge to it. I am not sure whether this is due to the pressure treatment or just the colour of the wood itself! What i am trying to find out is does this fade in time? How much time? or would you expect to paint or stain it. I am just after a natural wood colour. 

An example of what i am looking at is "Fence Panel Pitsford Pressure Treated 1800mm x 1800mm" on Travis Perkins.

Everything i have read implies that you need to dry pressure treated wood for months before you can paint or stain it.

    Wood used to have that green tinge because it had been treated with arsenic for a preserver, don't know what they use now but it does go completely away.

    I don't know about painting it, I always like to leave wood, wood colour.

    The wood has been "tanalised". It has been given a treatment to prevent it rotting and prolong its life. Untreated wood will rot in a couple of years. Tanalised wood will last much, much longer. The green tinge fades to a dull grey colour in about a year or so which looks quite natural and needs no additional treatment.

    That's the word Pansy, couldn't think, they used to use arsenic, same colour.

    Arsnenic has been banned for tanalising in Europe since 2006, although the current tanalising process has been found to be less effective without the arsenic content. The replacement process -  Tanalised E - uses copper and triazole biocides - an organic anti fungal treatment commonly used to protect food crops.

    NEVER burn any kind of tanalised timber such as old painted timber or boards, which contain formaldehyde resins (i.e. most plywoods, chipboard, and mdf). Tanalised E may be burned in approved industrial incinerators only, but should not be burned in open fires or home wood burners.
