Two short stanzas, and almost everything in them is left unsaid. The speaker describes a kiss so light that it needs no words; what it communicates is simply "ourselves," the two people involved. There is tenderness here, and a sense of closeness that talking might spoil.
The second stanza darkens the scene. The ink of night is "lost" in a woman's mourning gown, as if the night's blackness has been absorbed into her grief. The title, "Black is the color," ties the images together: the dark of night, the dark of the dress, and perhaps the dark mood behind the kiss. The poem suggests that love and loss are present at the same moment, though it never says why she is in mourning.
The mood is quiet, hushed and sorrowful, but gentle rather than bitter. The kiss feels like a small comfort held inside a much larger sadness.
