Some flowers come to mind.
They have all turned gray.In fact, I can't remember what those colors look like. At this time, in my eyes, everything is gray, including my emotions.
The gray flowers have lost their fragrance.
They become so unreal in my mind.
I used to be so close to them that I could smell their fragrance, hear the breath from the petals, and feel the marks left by the bees on them.
Those are flowers, not the same as leaves.
Even if it loses its color, it is also different from the leaves.
