I decided to go not only with the colour, but also with probably the most famous yellow object: the yellow submarine. It's fairly accurate to that found on album covers and in the movie, at least as well as I could do in one square inch.
Let's hope for a nice sunny week (not forecast in my immediate future according the Weather Network. Fog seems to be most called for, but at least that means it's fairly mild. Ah, mid December in Southern Ontario. Bring on April)
