Juicy looks normal.
Nice try Suomynona…
I’ve noticed when getting newer/fresher bottles of certain concentrates, they’re more clear than what I have on hand. I’m not sure why they get darker or yellow’er. The Inawera Strawberry they sent you probably sat around a while. Hardly anyone orders it. People are convinced Shisha is superior and there’s no need to try it.
I have both of those flavors but only in 10ml bottles right now. FA Juicy Strawberry is yellow like in your picture. INW Strawberry is mostly clear with just a little bit of yellow tint. I can see it getting darker with some age. I took photos but the lighting in my home makes everything look yellow.
A few years ago, I bought strawberry flavour from a french producer (Solubarome). It was yellow from the beginning, did not change its colour over the years, and it it completely okay, even now after ~ 3years.
So I would give your flavours a try, they might be just alright.
