fe + trace solution colour

I wonder what are the colour of these Fe + trace fertilizer solutions are:

1. TMG --> yellowish brown
2. Seachem --> dark yellowish brown
3. Plantex --> yellowish brown --> eventually rusty brown
4. Dupla ---> brown
5. Azoo ---> rusty brown
6. JBL
7. Niche ---> rusty brown
8. etc

please feel free to continue the list with the current Fe + trace liquid fertilizer you are using now.

Why did I ask this? because colour can determine what is inside (even though some might use colouring agent to cover up/cheat). I feel that I've been cheated by some light coloured yellow fert which is even more transparent than urine.....

No offence as I will never let anyone know what is the product I'm putting into doubt of. Why??? because it is not just me, my friends are also putting doubt

When I mix 1/8 tspn of Plantex CSM+B+Fe into my ~1cup of hot water, the mixture turns yellow. The powder itself is brownish.

thanks. Perhaps it just about those different formulations used and differet compunds for the same active ingredient that makes up the colour. Ok keep em coming... (some products are just much worse than the other as some experts have proved right here)

When I mix a stock solution of CSM+B+Fe it is green but after a while it turns a nice rust color.

Perhaps it is because you peep it into the dark bottle? Or maybe the bottle is frequently opened which may cause further minor oxidation and change the colour darker?

The product that I use (is not one of them stated above) does not look too concentrated and the very light yellow colour does not darken over time. In one of the bottles that I have, there are even contaminants algae-like stuff inside by the time I open the virgin seal ... what a shame they should've replaced it to me tenfold!

Ok... keep them coming folks.... so I can speculate and find out. Thanks in advance!

don't know why it's so dark... i presumed that it was always this colour and it has been since i bought it last weekend.... this is my first time using flourish... i looked again and it's very dark - almost black - and smelly....

does anyone know if this is normal?... now i'm starting to get a little worried?!

EDIT: Ok, I just checked my sources and Seachem Flourish is supposed to be dark (like soy sauce).... It also has a distinctive odor!
