This is actually the very first photo I took in this year's colors photo challenge, back when I was looking for Aquamarine. It wasn't at close to a match, but I held onto it, hoping it'd come into use later. I think it works nicely for sky blue.
To finish the pre-dawn hours of 5AM and 6 AM, I'm completing the four corners of Bay Station. Many of the intersections along Lincoln, a main thoroughfare across Alameda, have "station" names to match the cross street where there used to be streetcar station. My intersection is named Bay Station for Bay street. For 5AM I captured my third corner that contains a very popular shop that buys and sells collectible shoes. For 6AM I captured the fourth corner that houses a small local corner shop. There are many of these small shops down Lincoln avenue.
