The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light absorbed, and so it looks pink.
The correct electronic configuration of Ti(Z= 22) atom is: (1) 1s 2 , 2s 2 , 2p 6 , 3p 6 , 4s 2 , 3d 2 , (2) 1s 2, 2s 2 , 2p 6 , 3p 6 , , 3d 4 , (3) 1s 2 , 2s
