The Block Party Chartreuse Yellow Sports T-shirt is dressed for the court — just not the one you’re thinking of. A dense column of overlapping abstract shapes — rounds, rectangles, blobs — crashes down the right side in every color imaginable against a chartreuse yellow base. Same color as a tennis ball. Considerably more interesting than one.
Made from 100% recycled polyester mesh with moisture-wicking fabric and UPF50+ protection. Built for the gym, the run, or anywhere you feel like being the most interesting person in the room.
Unisex fit, available in sizes 2XS to 6XL.
Chartreuse yellow is the color of a tennis ball. It was chosen for tennis balls because it’s one of the most visible colors the human eye can detect. Turns out it’s also one of the most extraordinary bases for abstract art we’ve ever printed on.
Block Party is an original digital artwork by Melbourne artist Bert Ernie — a dense, layered composition of rounded rectangles, circles, and organic blobs stacking and overlapping in translucent layers. Against chartreuse yellow, the design crackles with energy. The greens in the composition blur into the base and disappear. The purples and blues push against the yellow with maximum contrast. The pinks and corals light up like neon. It’s the most visually electric of all the Block Party variants — which, given the competition, is really saying something.
The design column runs down the right side of the shirt — shoulder to hem, wrapping onto the sleeve. Front and back panels meet at the seam and mirror each other, creating a totem-pole effect at the join that rewards a closer look. The Wild Peach logo sits embedded in the design in matching chartreuse yellow. Subtle. Deliberate. Very much there if you’re paying attention.
People will notice. People will ask. You’ll probably get stopped at the shops.

The Block Party Chartreuse Yellow Sports T-shirt is handmade from soft, fade-free premium mesh fabric by our partners in Europe or the USA. The design is original digital artwork by Melbourne artist Bert Ernie (yes, that’s his real name). Unisex cut, 11 sizes.
