Nothing in "My Summer Rainbow" is named except the one thing that has gone. The speaker never says what the rainbow stands for, or what happened between the bright days and the sad ones. We get a before, an after, and a confession in the middle: "I have took my life for granted." The poem is about that gap, and about how happiness is often recognised only once it has disappeared. For a poem of seven short lines, it leaves a surprisingly clear mark.
The construction is a small collapse. The opening lines are full and confident: "The brighest colors filled my mind. / Colors with the brightest lines." Each runs to roughly seven syllables, and the repeated "brightest" piles the brilliance up, as if the speaker could hold the memory steady by saying it twice. Lines three and four are slightly longer and heavier, weighed down by self-blame. Then the poem shrinks: "All that was then, / Now is gone." Four syllables, then three. The lines fade on the page the way a rainbow fades from the sky. The last line swells back to nine syllables and finally releases the word "rainbow," which appears nowhere else in the text. The poem's central image arrives only at the moment it is lost.
There is no regular rhyme scheme. "Mind" and "lines" share a long *i* sound, a half-echo that suggests a pattern is about to form, but nothing else answers it. The ending has no chime to close it, which suits a poem about something that cannot be recovered. The rhythm is loose and conversational, closer to someone talking than to measured verse.
The imagery is more unusual than it first looks. The colours are located in the speaker's "mind," so the brightness was a way of seeing as much as something seen. "Lines" suggests the bands of a rainbow, but also sharp outlines and clarity. Yet after line two the poem never names a single colour. No red, no gold, no blue. Once the brightness is described, the vocabulary drains away into abstractions: "life," "sadness," "gone." The poem loses its colour at the same pace as the speaker.
The key words work as pairs. "My life" appears twice, first as something taken "for granted," then as something to be suffered. The repetition makes the link between the two lines plain: neglect leads to pain. "Suffer my life of sadness" is an odd phrase, since we normally suffer an illness or an injury, not a life. It makes sadness seem like a condition that has taken over everything. "Then" and "now" set the two time zones against each other, and "Now" opens two of the last four lines, as though the present keeps interrupting. The speaker also blames no one else. This is regret, not bad luck.
The nonstandard grammar and spelling add to the plain, unguarded voice. "I have took" is not standard English, and "brighest" and the lowercase "i" in line four look like slips. Whether they are deliberate or not, they make the speaker sound unpolished and direct. A reader may also notice that the capital "I" of lines three and seven shrinks to a small "i" in the very line where the suffering is stated, though that may be an accident of the text.
The phrase "my summer rainbow" holds a quiet irony. A rainbow is made of rain and light and exists only briefly, so it is lost almost by definition. Summer, too, is a season that ends. Calling it "my" rainbow claims ownership over something nobody can own, which is a version of the very mistake the speaker admits to. The speaker treated a passing thing as permanent.
The poem is not complex or technically ambitious, and it does not need to be. Its value lies in how closely the form follows the feeling: bright repetition, then admission, then lines that shorten until little remains. It offers no consolation and no lesson stated outright, only a speaker who now sees clearly what was there. That honesty, and the single image carrying it, is what gives the poem its weight.
