Glow Worm

Glow Worm always reads like a lighter spring green with a soft, pearly lift. It feels less grassy and less yellow-leaning than Frog Prince, and it doesn't carry the laid-back gray cast that Cool as a Cucumber has. Compared to Badass Grass, it comes off more friendly and buoyant, not sharpened or "trying hard." The undertone stays distinctly green, but it's toned up in lightness, so it lands closer to sunlit foliage than warning-sign energy.

I reach for it in product UI when you want a primary green that feels the one you reach for without tipping into urgency. Think wellness and lifestyle platforms, menu highlights in food or agriculture dashboards, and onboarding or progress states where you want momentum that still feels calm. It also works well in retail promos and lifestyle app thumbnails when the layout uses neutrals and you need that green to pop without getting loud.

One quirk: keep it away from very pale creams unless you add a touch of contrast elsewhere, because its brightness can make it blend at small sizes.
