One wall in the new kitchen in River Drive ca.1999 had to be cobalt blue. I dunno why; mine is not to reason why. Aitch said it must be cobalt blue and so of course it was. Some of the other colours she and Nanich painted the house were also to dye for. See below. Lucky I’m a mild-mannered diplomat.
So when the post-Aitch renovations happened ca.2012 in Elston Place, there had to be some blue. I made the scullery and laundry doors blue. I looked for cobalt blue, but this was the closest I found.
