The correct answer is - It becomes colorless.
Perfectly octahedral [Ti(H₂O)₆]³⁺ is violet in color. Upon heating, it loses its water molecule from the coordination sphere. There is a transition of electrons from t2g to eg orbital. The splitting of the d-orbital takes place.
If a complex distorts from regular octahedral geometry, the t2g and eg levels are split and the consequence of its appearance changes. Therefore, when [Ti(H₂O)₆]³⁺ is heated, the color changes from violet to colorless.

Hey !!
On heating, H₂O is lost. In the absence of ligand, crystal field splitting does not occur hence the substance become colourless.
Good luck !!
