Meg I have done a lot of monochrome painting (black and whites), because sometimes the effect is more dramatic. Have a peek at my website under Figurative and you will see what I mean. It is wonderful that your client is presenting you with a little challenge to do s.th different.
When I used to do outdoor shows there were always those people who gravitated to the monochromatic paintings better the colored ones. So it is really a matter of personal taste.
These type of paintings are the best studies in value control and I have found them to be a huge part of learning how to paint better.
Can't wait to see what you will paint!
