Fish Turning Yellow?

[Guppy P]

Ok... I was recently looking at my four guppies, and three of them are looking a little yellow. The two female's tails are a light, tinted yellow, and one of my males who used to be a shimmery light aquamarine-like color has the same tint on his sides now...

Is it a bacteria or something like ick?
Is it the food?
Is it the water? (I just changed it yesterday)
Or is it just their natural colors changing?

I use Jack's Aquarium & Pets Color Flakes with Color Enhancement and they eat it perfectly fine. My other male remains the same color as I bought him.

Please let me know if you can help and if anyone has any suggestions!!!

More then likely just their natural colors coming out. How long ago did u purchase these fish?

Exactly three days ago. I don't know if the females being pregnant have anything to do with it, but they are all full grown, too.

When fish are shipped around and bought, they get very stressed out, and with this, they loose their color. After a couple of days they will get their natural colors back. So I bet that is what you are seeing.
