That combination suits app and product marketing, event posters and social media graphics, and it is a good fit when you want a design to feel crisp, modern and high-energy.
Accessibility and contrast
The strongest pairing is Sky (#3DD6F5) with Teal (#1B737B) at a contrast ratio of 3.20:1, which is WCAG AA large. Across all 10 possible pairs, 0 reach the 4.5:1 AA level for normal text and 1 more reach 3:1 for large text.
No other palette color reaches 4.5:1 on the background (#3DD6F5), so this page suggests #011F22 for text, a darkened Teal that reaches 9.94:1. Check any pair you use in the contrast checker.
All five colors stay distinguishable under protanopia, deuteranopia and tritanopia simulations, which is a good sign, although it is no substitute for testing with real users.
How to use it
Suggested roles: #3DD6F5 as the background, #1F89A5 for cards and surfaces, #2FBDE6 as the primary brand color, #20A2B3 as the accent, and #011F22 for text (a computed darker shade of Teal, because no palette color is readable on that background). A reliable starting split is 60% background and surface, 30% primary and 10% accent.
Use the lightest color for large areas, the mid tones for structure, and the darkest for text. Add contrast through lightness, since hue will not do it for you.
Typical uses for a vivid palette include app and product marketing, event posters, social media graphics and entertainment brands. Open it in the generator to lock the colors you love and reroll the rest, or in the visualizer to see it on real layouts.
