Best tones or something
 

Just pick. I'm in a debate...

Hmm.........

It really just depends on the person you're trying to convey that image to. My guess is that old people would like black and white the most as well as sepia (but not as much), emotional people would love color the most.

I personally prefer colored with the scale shifted over to blue.

I prefer gray-blue, with a tinge of green.

The blue makes it look cold, the gray makes it look less regal, and the green makes it look less noble.

I like silver-blues, dark blues and blues, silver-dark blues, blue-black, lol. I'm a blue person. :p

Que Passa!!!!

Call me an old fart in a young body, but black and white just speaks to me better (I don't really think in color, but in this modern sociaty people like it better, so I comply.)

Depends on the picture. You can use a colour, but still make it monotonous. A grey-blue, but no other colours, will make something look cold, eerie and gloomy. That's the sorta thing I like, but it depends on my mood.
