Almost Blue

I step off a green tram onto a blue bike. The blue of the bike is the exact hue of blue of the car I’m searching for: the blue of the chalk - that is the bike - is the exact shade of blue used (painted) to define the parking spaces. But I’m in a park, not a parking space. On exiting the park I’m once again forced to photograph a car that’s hue of blue is closer to, but still not true to the blue of its parking space.
