Tropical Paradise Palette

Using this palette

Two teals anchor this rather than one, because tropical water genuinely shifts between a deeper channel teal and a brighter shallow-reef teal, and collapsing that into a single blue-green loses the effect. #FF6B6B and #FFD166 are the 'flower and sun' accents — use them in small, high-impact doses (a CTA button, an icon) against the teal fields rather than as large backgrounds, or the palette tips from tropical into simply loud. #F0F3BD is the only pale swatch and works as a sand-colored background that keeps the two teals from clashing directly against pure white, which reads slightly cold next to this particular green.
