Thats just one pheno type and ofcorse its difficult to judge by picture alone. With colour on pictures as comparison it wouldnt be fare as ive seen grows from nl5haze that look paler like yours( yours is a good more sativa pheno its similar to some of the potent sativa phenos out of proper nevils haze) but ive seen grows were the leaves come up darker green aswell. Ive even seen wen nevil was growing it at sensi ( might still have pics of the rooms somewere il have a look). You could tell the 5haze in veg at sensi as the plants were the ones, dark leaves and they were always up to the roof and like 3-4 times the size of everything else. Haze C in the veg room when nevil was at sensi still took up all of one side of the room ( might still have a pic were you can see haze c at sensi those times too, if i find one il put it up). Diffrent feeding ect can all change the colour. I do agree good 5hz c buds were a brighter lighter green, swamis bud in your pic looks like it leans towards the nl5 cut. Also its not always easy for some people to grow f1 5haze and get it coming out looking good, ive seen plenty guys make it come out like hay . I do agree with you that swami messed theirs up as from multiple grows ive seen it looks like he has got rid of all the more satva phenotypes and locked it down to the shorter faster flowering types and mid range types.
I still got axces to flower from a couple f1 strains to smoke now and then. It just takes long to grow some of these great sativa leaner plants so i dont get those as often as id like.
