The color of the hydrated ferous ion [Fe(H2O)6]2+ is actually violet.
However, most solutions contining the ferric ion are usually yellow or
yellow-brown due to the formtion of species such as [Fe(H2O)5(OH)]2+, and
solutions of the ferric ion can be quite acidic due to the reaction with
water.

你自己读读你摘的这句话。第一句说的是二价铁,第二句说的是三价铁。因为是三价铁
,所以显yellow或者yellow brown.
[Fe(H2O)5(OH)]2+你算算这个铁是几价。

上次抄的有误,violet是ferric,而不是ferrous……
The ferrous ion is greenish in solution, while the ferric ion is a light
violet. The distinct colors of iron compounds are due to the d-electrons,
which can interact with light in many interesting ways. Ferrous oxide, as a
mineral, is called hematite ("blood-stone") and is usually almost black. It
leaves a red streak on unglazed porcelain, and in its usually finely-divided
condition is a characteristic bright earthy red. In pure form, it is called
rouge, good for reddening cheeks and polishing glass, or Venetian red, a
red pigment. The red stains on concrete are ferric oxide, usually from
reinforcement rods that are not properly protected from the weather. The red
of Mars is ferric oxide, showing that the atmosphere once contained oxygen,
the oxygen that is only liberated by life.
