Why isn’t cobalt hydroxide pink in color?

Why isn’t a pink product obtained during the synthesis of cobalt hydroxide?
Processes such as synthesis and filtration are prone to oxidation, resulting in the failure to obtain pink cobalt compounds.
Cobalt hydroxide exists in two structural forms: α and β. The β form is pink, and the phase transition can be controlled by adjusting the pH value
Alpha-form cobalt hydroxide is dark red. It’s normal; both the pH and temperature need to be controlled.
