Today’s color prompt can be taken literally or figuratively! You decide!
You could photograph a collection of blue items you may have; for example, a set of dishes, an array of yarns, a handful of seaglass, etc
Or
You could make a collection of the blues you find as you go through the day! Consider creating a collage or a flatlay to show them off.
I ended up having a very blue day! My collage included flowers along the sidewalk, a trip to the store, the rising moon, and a stroll on the beach.
What Blue's did you collect!
