First thanks to everyone for their vote and comments, taking it all into consideration I am still undecided. I have opted for the colour ones on my P411 & Date-check profiles so that might sway me to put B&W on the website.
Please forgive me for not using the "quotes" in this response but it's just easier for me to edit this way.
Licking-Gravity said "I kind of like it every once and awhile but would regret all escorts adopting this style."
I think this is what has me leaning towards using the B&W's, there are not many ladies out there that use them and I do feel it is a little more reflective of who I am so perhaps that is a differentiator. If everyone was using that style I might reconsider and lean towards full colour but I am not sure it is.
Anna mentioned "Does arty sell in this industry? Yes and no, but I think when it comes down to it in this industry, color would probably sell best."
Just as an FYI the photos I receive the most positive feedback on have been my B&W's (eg.

Madman - no the photos are not taken in my place. I would never do a shoot in my personal home as I value my privacy and discretion too much for that and I do not keep a separate incall, I work far too infrequently for that to be economical. It's at a hotel, if you want to know which one PM me and you can book a room there and admire the faucets and flooring... you can even get your own photographer and recreate the images with you posing (a la this...

To those that said they love my body - See T-Boys response, I would like to think that it's my personality and the environment I can create during a date that is what sets me apart, physical attraction is just icing on the cake.

And to those that said they'd like to see me naked... well that's not really hard to arrange. I did post a full nude yesterday so if you are looking for the free version that is probably the only way you'll see that.
I guess the one thing I need to decide and the thought that keeps coming up as I read this thread is how many of the posters that prefer colour and how many that prefer B&W would actually book me anyway? Online it's hard to know who is my market and who is not (and I'm well aware that I have a specific appeal/niche market). I suppose that is what I would need to figure out in order to effectively answer the question.
All the feedback has been helpful and appreciated. I have never struggled with making a decision on my photos before so this is somewhat unusual for me and I am grateful for the help.
