Intro
Some names stop you cold. Stonefly Plumbing is one of them.
I came across it on Facebook — a local plumbing company with a name that sits at the intersection of two worlds that almost never meet: fly fishing and plumbing. A stonefly is one of the most important insects in fly fishing, a nymph tied to hooks and drifted through cold mountain streams. It’s also, apparently, the name of a plumbing company. That overlap is rare, specific, and genuinely ownable. The kind of thing a brand identity can be built around.
The problem was the logo they had.
Project Scope
- Deliverables: Logo files and assets (raster & vector), Brand Guide (PDF)
- Tools: Adobe Illustrator (design), Claude (ideation)
- Role: Creative Director, Designer

THE ORIGINAL MARK
The existing logo was AI-generated — and it showed. A circular badge format packed with a fishing rod, a detailed lure illustration, a mountain landscape, pine trees, a water splash, and a copper pipe. Everything the prompt likely asked for, rendered in full photorealistic detail with a beveled 3D wordmark across the middle.
It’s a good example of what AI logo tools actually do: they respond to prompts literally. Ask for fishing and plumbing and you get every fishing and plumbing element the model knows, layered into a composition that tries to be everything and ends up owning nothing.
Beyond the concept problem, the execution created real practical issues:
- Raster-only output. A PNG is not a logo. It’s a picture of a logo. No path data, no scalability, no future.
- Unreproducible in print. Photorealistic gradients and fine detail cannot be screen printed, embroidered, engraved, or stamped. The mark only exists on screen.
- No color system. No Pantone, no CMYK values, no way to reproduce the colors consistently across vendors.
- No variations. One image. No horizontal lockup, no single-color version, no reverse, no icon-only crop.
- No usage guidelines. No clear space rules, no minimum sizes, nothing to protect the mark as it moves into the world.
- Generic format. The circular badge with a landscape inside is one of the most common AI logo outputs in existence. It looks like thousands of other marks generated with similar prompts.
The name deserved better. So I decided to build something.











Finding The Concept
The first instinct with a name like Stonefly is to go overhead view — wings spread, insect silhouette, the obvious read. I explored that direction briefly and set it aside. It was already the territory of the original mark, and the dragonfly shape it defaulted toward wasn’t even the right insect. A stonefly folds its wings flat along its body, torpedo-like, completely different from the spread-wing silhouette everyone reaches for.
More importantly, the overhead view gave me nowhere to put the plumbing reference in a way that felt integrated rather than tacked on.
The pivot was thinking about the mark from a fly fishing perspective specifically — not the insect, but the lure. A stonefly nymph tied on a hook, seen from the side. Profile view. That’s the angler’s perspective, the fish’s perspective, the way the lure is designed to be seen.
Profile view gave me everything:
- A distinctive, less expected silhouette
- A horizontal format that would own a truck door
- A natural place to introduce the plumbing reference
- Motion — the sense of something drifting in current
The concept locked in when I realized the hook and the P-trap are essentially the same shape. A P-trap — the curved drain pipe beneath a sink — follows the same bend geometry as a fishing hook. Swap one for the other and the lure still reads as a lure, but the plumbing reference is unmistakable to anyone who looks twice.
That’s the right kind of concept. You read it as a fly fishing lure first. Then your eye finds the P-trap and does a double take. The discovery sequence is the whole point.

Building the Mark
The process was iterative, working from a simplified silhouette base toward something that could survive every print scenario it would face.
Early versions carried too much detail — wispy hackle fibers, delicate wing strands, body texture that read beautifully at large scale and would disappear completely at an inch wide. The mark needed to be simplified to its essential shapes: the body mass, the segmentation, the bead head, the hackle suggestion, and the tail fibers. Each element reduced to what it needs to be, not what it could be.
The P-trap went through several rounds. The first attempts read ambiguously — too small, the wrong shape, terminating in ways that created unintended silhouette problems. The final version is correctly scaled, maintains a consistent pipe diameter through the curve, and terminates with a flat stub and fitting detail that signals plumbing without explanation. The fitting rings at the connection point between the lure body and the trap are doing real work — they’re the thread/nut detail of a pipe joint, which also happens to reference the thread wrapping of a tied fly.
The mark was rotated clockwise until it settled at a slight natural angle — head lower than tail, the way a nymph actually drifts downstream. That angle gives the mark energy and movement without feeling aggressive.

The Color System
The palette was already suggested by the original mark’s better instincts — navy and copper. The new system formalizes those instincts into something reproducible.
Current (PMS 655) is the foundation. A deep, rich navy that carries authority and trust — exactly what a trades business needs to communicate. It anchors the lure body and the primary wordmark.
Copper Run (PMS 7575) earns its place twice. It’s a literal plumbing material reference and the color of fly tying thread and dubbing. It also happens to be beautiful alongside deep navy. The key decision was assigning Copper Run specifically to the P-trap and the word PLUMBING — color is doing conceptual work here. Your eye goes to the lure body first, then finds the copper trap. The color leads the discovery. That echo carries across the horizontal lockup: copper trap on the left, copper PLUMBING on the right. The system is coherent.
Live Copper (PMS 875) is the metallic variant, reserved for applications where metallic ink is available — foil stamping, high-end print collateral, embossed business cards. Where metallic isn’t possible, Copper Run steps in. The brand never loses its warmth either way.
CMYK values for all three should be derived from the Pantone references rather than from screen — the only reliable way to keep warm browns and rich navies from drifting in print.







Why This Matters
AI logo tools are genuinely useful for a lot of things. Brand identity isn’t one of them — not because the outputs are always ugly, but because the process that produces them skips every decision that makes a mark actually work.
A logo isn’t a picture. It’s a system of decisions about what a business is, what it communicates, and how it survives contact with the real world — the truck door, the embroidered hat, the yard sign, the favicon, the business card. Every one of those applications has requirements that a single AI-generated PNG cannot meet.
Stonefly Plumbing had a name worth building around. It just needed someone to do the building.
This project was completed on spec. The brand identity package — including all production files — was offered to Stonefly Plumbing as a gift, with any compensation left entirely to their judgment.
