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.
Urea or Carbamide - Carboxylic acids Urea may be referred like a diamide of an unstable and dibasic carbonic acid by which both the hydroxyl groups have been changed by -NH 2

The uncertainty in momentum of an electron is 1 x10 -5 kg- m/s . The uncertainty in its position will be (h= 6.62 x 10 -34 kg - m 2 / s): (1) 1.05 x 10- 28 m
Mostly compounds of d block elements exibitcolour dueto d-d transistions between partially filled eg and t2gbut the reason for colour of KmnO4 and K2Cr2O7 is due to partial chanrge transfer between central atom and oxygen which causes colour
