I do the same. I dress all my Elders in white, my doctors in black robes, my farmers in green and my builders in all blue. I talk to my villagers too (usually not very nicely most of the time because they insist on going off and doing what THEY want to do and not what I want them to do).

I really think I should get a life but, since I lost my job last year and am finding it very difficult at my age (56) to get another one, this is what's keeping me going at the moment.
