I’m not sure which version I prefer. Certainly the idea of purity is better represented by the black and white version. But I really liked the play of color in the reflections on the metal chairs. I boosted the contrast and the vibrance in Lightroom before converting to B&W in Perfect B&W with the Vivid Dream preset, then masked out the B&W on the chairs and reduced the opacity of the effect somewhat, brought back to Lightroom, reduced the contrast a little and raised the clarity and applied a dark vignette. Then I made a copy, converted it to B&W and played with the clarity and contrast a bit for the B&W version.
