Color or b/w? Or not at all?
Colour, this one, because I think it's more interesting that way.
B/W is a funny thing: sometimes it makes an image but at others, it leaves it flat. I suppose the simple truth of the matter is that it really depends what drew one to the shot in the first place. I believe that subtle colours can work very well, where often, that's not so in B/W where a good bit of 'kick' often makes things sing out loud. Generally, I think silhouettes, for example, work better in B/W but no doubt there's a million instances where cosmetics ads prove otherwise. It all comes down to the specific instance, kid brother to the decisive moment. Only in photography.
I remember trying desperately hard on one occasion to get a girl in front of the blue haze that film used sometimes to rewards one with on distant mountains (mostly folks want to filter it
out) and shooting with a 200mm on Nikon, I eventually did make the shot. In B/W it would simply have looked flat grey - no real suggestion of spatial distance at all.
