What color scheme to use

I have 2 thoughts about what color scheme to use for a night time snow image for my recycle piece. Should I go with blues or grayscale. If I do grayscale the streetcar would still be red. Almost like it’s in an old black and white photo. I suppose the decision will be made for me by what plastic bags I have. That’s what I’ll be looking at today. 

Here’s the photo I’m working from and AI images showing the color schemes. I do like the blue one better, but blue bags are harder to come by. I do have a lot of gray bags left over from last years Raven piece.

The decision may be out of my control.

Thanks for reading.
