KFe(CrO4)2 very easy
Today I read about a compound whose formula is NH4Fe(CrO4)2. It was written that this compound is red. I do not have ammonium chromate, so I used
potassium chromate. The reaction proceeded as follows:
2K2CrO4 + FeCl3 = KFe(CrO4)2 + 3KCl
I thought it would be dark red but it is dark brown. If you observe some particles reflect light. In fact, they have a darker color and a metallic
sheen.
If you want nice inorganic compound. Then use ammonium, I think it will have a nice red color. As you can see, potassium does not have a charming
color.

Is it water soluble, very sparingly soluble or insoluble?

I don't think that ammonium salt look different.

The source wrote that it has a red color. Many compounds have a similar color, but it may be really red and the source is not mistaken. For example
potassium tetrachlorocuprate differs in color from ammonium salt.
