Thanks to Arlee at http://arleebarr.squarespare.com.designjournal I have been playing with colour at www.colorstrology.com and find that my colour is Autumn Leaf. Note the colour of the font in this blog.
This is really strange because there is a paint site that I play with and invariably whatever my answers the colour scheme that comes up time after time for my interior decorations is natural stone shades, creams through browns. And actually, although I don't dress in these colours, I do feel most comfortable living in rooms with this colour scheme. Maybe there is really something in it.
