Sulphuric

Sulphuric always reads a touch more lemony than the pale greens I expect. It's not chartreuse-bright like Pineapple High, and it doesn't hover in that soft, almost-neutral yellow haze like Crash Dummy. Compared to Honeysuckle, it feels noticeably lighter and more saturated, with a cleaner, dryer warmth that makes it look more deliberate than a sunny sticky note.

I use it for UI moments that need small emphasis without going alert. Think warehouse and logistics status chips, pharmacy or food-service inventory step markers, and e-commerce product-card highlights where you want "active" to feel cheerful but still controlled. It also works well on onboarding screens as a the one you reach for tint behind short instruction blocks, especially when the rest of the palette is cool or neutral.

Quirk: on very white backgrounds it can look a bit flat; a faint green border or a slightly deeper gray line keeps its edge crisp and prevents it from drifting toward the softer yellow end of the family.
