Heat Wave

Heat Wave reads like that first bright flare you see off a roadside sign at dusk. It's noticeably lighter and less heavy than Butternut Squash, so it won't sink into that grounded, food-rooted depth. Compared with Arancio, the undertone feels more energetic and less terracotta-clay, with fewer "red bleed" cues. And vs Habañero, it comes off slightly calmer in intensity, more sunburnt warmth than spicy forwardness.

I use it when I want a high-visibility highlight that still feels friendly in interface surfaces: e-commerce category headers, seasonal promos in retail, and product hero CTAs for food and travel brands. It's great for states where you need urgency without the darker punch of deeper oranges, especially filled buttons and active chips. Think the one you reach for when you want heat to read clearly on-screen without tipping into that "too hot" feel Habañero can get on very light backgrounds.

Pair it with warm creams or soft charcoals, and watch contrast with thin UI text. If you're layering over busy imagery, it holds up better when you keep the surrounding neutrals clean.
