For us here in the Northern hemisphere summer is such a great time for yellow week.  Yellow is such a summery colour.  I'm sure you will find a bounty of yellow objects to grab your attention today even if you are not in the grips of summer where you live.  

We have this great sunflower field close to our place and I love to visit it every year to take photos.  The bees love sunflowers and they find a bounty of nectar and pollen in them.  It's a feeding frenzy of yellow!
