Chromatic aberration, it'll reduce in LR/PS but some cases can be tricky to completely eradicate. Occurs around high contrast edges, can come in a few different shades, some lenses do it in Out of focus areas where it will often be green one side of focal point and purple the other, others do it in red or blue depending whether it's along a horizontal or vertical edge, some just do it in plain purple.

To add to this LR and camera raw have some profiles for specific lenses that can help reduce common occurrences automatically that then require minimal fine tunning. A quick google will provide you with quite a few tuts on this subject.

What lens/camera is it?

CA is something you won't see on many of the better Canon/Nikon long lenses and Nikon's newer bodies actually remove it in software automatically pretty well.

thanks for the advice if it may happen in out of focus areas what kind of focus set should i set the camera to? would it have anything to do with it being a sunny day? my camera is a sony a200 and it was sonys own 300mm lens f4.5-5.6 heres the pic in question if you look at the white line you can see it and the white lettering on his leathers on the bottom of cals back. it doesn't look so bad oh hera but i had a 30x20 inch poster made of this image and it seems to show more on there. don't know if im being over fussy or weather its my camera at its limit? :shrug:

Its a lens thing... Doing some Google it seems it is noted for it.

There is both firmware for later Sony cameras to remove it automatically like I said nikon do and a newer version of the lens itself which uses extra low dispersion glass which also fixes it. It's the glass seperating the colours out in the light like a rainbow that does it, usually most visible where dark meets light
