Think of this palette as a walk from the water into the leaves. Lagoon Turquoise is that first clear, shallow water you see in a postcard, and it leads the whole scheme. Jungle Green picks up right behind it, the way the tree line meets the shore, giving the brightness somewhere solid to stand.
Then come the flowers and the fruit. Ripe Mango adds a warm glow, and Hibiscus Pink is the single hot petal that wakes everything up. A little of each goes a long way, so keep them as small sparks rather than big fields of color. The contrast is the point.
Holding it all together is Deep Palm, a near-black green that reads as shadow under the canopy. It is the easiest way to make a bright tropical mix feel modern instead of cartoonish, so lean on it for the edges and the grounding pieces while the turquoise does the talking.
