Create a highly realistic vertical educational nature poster for primary school students explaining why leaves change color, styled like a premium botanical garden teaching display. Place the title “WHY LEAVES CHANGE COLOR” engraved on a tall wooden botanical garden sign standing along the right side of the poster, using high-contrast cream lettering and no subtitle.
Build the entire composition around one large realistic tree branch stretching diagonally from the lower left to the upper right. Use this single branch as the visual journey, showing a smooth seasonal transition from deep late-summer green leaves to yellow, orange, red, and brown autumn leaves. Keep the reading flow diagonal from left to right, and avoid equal timeline boxes, human characters, soil cutaways, or top-down science-table layouts.
At the lower-left start, show healthy green leaves in bright late-summer light with the label “1. GREEN LEAVES” and the sentence “Chlorophyll makes leaves look green.” In the center-left, show the same branch as the season begins to change, with slightly fading greens, labeled “2. SHORTER DAYS” and “Less daylight tells the plant that seasons are changing.” In the center, include a magnified leaf inset showing reduced green pigment, labeled “3. LESS CHLOROPHYLL” and “The plant makes less chlorophyll in cooler seasons.” In the center-right, show more yellow and orange leaves appearing, labeled “4. OTHER COLORS SHOW” and “Yellow and orange pigments become easier to see.” At the upper-right end, show vivid red, orange, and brown autumn leaves, labeled “5. AUTUMN COLORS” and “Many leaves turn yellow, orange, red, or brown.”
Add only three short supporting notes. Near one enlarged leaf detail, place “CAROTENOIDS — yellow and orange colors.” Near another enlarged leaf detail, place “ANTHOCYANINS — red and purple colors in some leaves.” Near the branch tip, add “Not all trees change color in the same way.” Use highly realistic botanical photography blended with natural-history poster detail, with crisp leaf veins, realistic bark texture, subtle seasonal light, and a believable gradual color shift. Set the background as a softly blurred woodland scene that transitions from late-summer green on the left to rich autumn amber and russet tones on the right. Keep all text large, clear, and easy to read at mobile and thumbnail size, with each explanation limited to one short sentence and each text element placed on quiet, high-contrast areas or clean label plaques. Maintain scientific accuracy throughout: do not suggest that paint-like colors are added to leaves, do not imply that all trees turn red, do not show chlorophyll as green liquid leaking away, do not treat temperature alone as the cause, and do not include smiling leaves or fantasy faces.
