if they would rise, let them rise;
the crimson
one dipping deeper still
you yourself have dyed.
Meaning: Let the white clouds rise if they will; for you have dyed the crimson one dip deeper still.
Commentary: Book One Spring Poems 20

Headnote: "Reply"
A reply to the preceding poem, it answers that the white clouds may come between if they like, since you have dyed the crimson one shade deeper. Taking up "has sunk deep into my heart," it rejoices that the flowers' color has deepened through the other's words.
The author is said to be the mother of Prince Yasusuke, and this poem closes the three-poem exchange that began with 18.

The first line, "as for the white clouds," takes up the fourth line of 18 and the first line of the preceding poem; through all three poems the white clouds are what come between.
The second line, "if they would rise, let them rise," uses an imperative to concede, letting them do as they will. The poem breaks here.
The third line, "the crimson," is the word shared by all three poems; here the weight shifts to crimson as a dye color.
In the fourth line, "hitoshio" is one dipping in the dye bath, meaning the color is deepened one degree further.
The last line, "you yourself have dyed," uses the emphatic particle "shi" and a definite condition with the realis plus "ba," meaning since it is you who dye it. "Crimson," "one dipping" and "dye" are associated words from dyeing.
