Picking out colours to pull contrasting clothes together

I would normally be wary of mixing an earthy green jacket with bright blue chinos (why I don't know, they are colours we see all around us on a sunny day). I noticed that my Harris tweed jacket has a thin line of the same blue woven into it which helps the two contrasting garments work together. Try this approach with completely contrasting colours where a co-ordinated look helps avoid an unpleasant clash of tones.

And yes, I did say I was putting the tweed jacket away for the summer - in doing so I annoyed the weather gods to the extent that London has been wet and cold ever since.
