That grey and yellow thing....A revival of 1950's styles in recent years first brought the grey and yellow combination to my notice, but not being a fan of that period I ignored it for a while. But I began to notice a rather lovely vibration between the two colours, especially if the grey was not a neutral grey - one made of adding white to black - but a grey with some colour in it, in watercolour paint Davy's Grey (yellowish) or Payne's Grey (bluish) and in fabric the colour known as French Grey (also bluish, sometimes purple-ish). With a very clear yellow as in daffodil yellow beside the pale grey kitchen tiles here it really works for me.
I went around the house today and see that I have quite a lot of grey and yellow things so I think I will gather them together and make it a new colour scheme for the sitting room for spring!
