Hemigrammus herbertaxelrodi - their stripe has turned from white to gold?

So I got some H. herbertaxelrodi recently. In the store, they had white stripes. When I added them to my aquarium, however, their stripes turned gold. The exact same shade of gold as the other Tetra species I have in there, Hemigrammus rodwayi, in fact. The H. herbertaxelrodi are now schooling with the H. rodwayi, too. I've actually had the H. rodwayi change a stripe to different colors before as well (bright orange and bright blue, when the wanted to school with Trigonostigma heteromorpha and Melanotaenia praecox respectively, most of them now have regular gold coloring again though). 
However, I've never heard of a H. herbertaxelrodi coloring changing in this way. Does anyone know if they will get their normal coloring back or not? If so, is there anyway I can make that happen? I've been excited about the H. herbertaxelrodi and wanting them for years, but with a gold stripe the black and white contrast I bought them for is ruined, and they just look like H. rodwayi with a black stripe now, rather dusky and dull compared to the black and white look. I'm really unhappy with how this is looking...:-? 
I only have 8 H. herbertaxelrodi right now, compared to 11 H. rodwayi I was planning on getting 11 H. herbertaxelrodi, but with them looking like this I'm not sure I want more. Would having more of the H. herbertaxelrodi maybe fix this?

  Here is a picture so you can see what I mean.  The Black Neons still have their regular black lower stripe, it is only the upper stripe that has turned from white to gold:

Hi Sarabi,

unfortunately, the only thing recognizable in that picture are your Trigonostigma but that's beside the point.

What's wrong with fishes changing color unless it's because they are not healthy? Do you stock your tanks by color scheme? Do they not compliment the wallpaper anymore? I'm sorry if this sounds a bit sarcastic but I really don't get your point!

Regards

R.

If you must insist on living in a box ...... at least do your thinking outside.

The colour you describe sounds quite normal, but if all the fish in the tank are appearing somewhat yellowish, perhaps you should look at the lighting you're using?

Cake or death?

Aye, lighting, substrate colour, maybe even the fact that they are happier (it's been shown that Neons can change the stripe colour in reponse to stress, no reason why other tetras shouldn't also).
