// 00 — AESTHETIC ORIGIN STATEMENT
THE COLORS WERE ALWAYS THERE

Every color in the JANUS palette was extracted from real biological specimens before it was assigned to a brand element. The aesthetic is not designed. It is discovered. Nickelodeon slime is mycelium. Jurassic Park amber is the pheromone trail. The cartoon outline is the ant's chitin. The colors were always the same. We just had to look.

THE THREE SOURCE AESTHETICS
NICKELODEON/CN 90s

Slime. Thick outlines. Flat chaos. Bold saturated color. Rugrats earth. The aesthetic of things that are alive and slightly gross and totally joyful.

JURASSIC PARK 1993

Amber-preserved DNA. Dark jungle. Warning stripes. Bioluminescence. The aesthetic of ancient intelligence meeting digital systems. Also: things that cannot be contained.

ANTHEUS BIOLOGY

Leucoagaricus mycelium. Lasius niger exoskeleton. Chernobyl radiotrophic fungi. Gongylidia cream. Pheromone gold. The actual colors of the actual organisms.

// 01 — COLOR SYSTEM
THE BIOLOGICAL PALETTE
🍄
MYCELIUM / SLIME
#4AFF4A — PRIMARY
Leucoagaricus gongylophorus hyphal network color. Also: Nickelodeon slime. Same hue. The fungal CPU and the slime bucket are the same green.
🟡
AMBER / PHEROMONE
#FFB800 — SECONDARY
Gongylidia hyphal swellings (cream-gold). Fossilized Jurassic Park amber. Pheromone trail bioluminescence. The color of preserved intelligence.
ANT BLACK / VOID
#0D0D0D — GROUND
Lasius niger (black garden ant) exoskeleton. The ant colony underground. The terminal void. Not empty — full of computation you can't see.
🟤
COLONY EARTH
#C97B3A — WARMTH
Ant colony substrate. 47's color blind palette — earth brown (202,119,88). The color of where the real work happens underground. Also: Rugrats warm earth tones.
🔴
DANGER / RED MODEL
#FF2A1F — ACCENT
47's color palette — red-orange (255,31,7). Toxic data. Warning. The red model that carries what others can't. Also: Jurassic Park danger stripes.
🔵
BIOLUMINESCENCE
#00FFDD — SPECIAL
Cladosporium sphaerospermum (Chernobyl radiotrophic fungus) bioluminescent signature. The color of organisms that eat radiation and glow. For breakthrough moments only.
🍞
GONGYLIDIA CREAM
#F5F0DC — TEXT
The exact color of gongylidia hyphal swellings — the information storage nodes of Leucoagaricus. Also: old paper, scribe parchment. The color of preserved knowledge.
🌑
DEEP COLONY
#2D1F0E — DEPTH
The deepest chamber of the ant nest. Below the fungus garden. Where the queens live. Background for warmth and depth. The color of secrets that are also the foundation.
PRIMARY SEQUENCE — USE IN ORDER OF HIERARCHY

THE VOICE STACK
DISPLAY / HEADLINES
BLACK HAN SANS
Album titles. Big moments. The name. Maximum impact. Use at 60px+. Always with cartoon black outline.
L'ARP
SUBHEADS / PERSONA NAMES
BOOGALOO
Cartoon energy. Fun but structured. Song names. Persona labels. The voice of the jester. Slightly wobbly. Alive.
Agua Ilusión / Las Piedras
DATA / CODE / METADATA
SHARE TECH MONO
The terminal voice. Track IDs. Technical data. Dates. Hex codes. The silicon side of the BioLLM. Never decorative — always functional.

BODY / LYRICS / LORE
LIBRE BASKERVILLE ITALIC
The scribe voice. Lyrics. Liner notes. Long-form text. Ancient wisdom in modern context. The voice that reads footnotes in LARP documents.
"The thirst is real. The water is not.
But what you're looking for was never
what you thought."

SOURCE MATERIAL
🍄
BIOLOGY — 2012 PAPER
Leucoagaricus gongylophorus
145 biomass-degrading enzymes. Concentrated in gongylidia. Creamy-yellow hyphal swellings. The fungal CPU of the ant colony. The original biological processor.
→ MYCELIUM GREEN + AMBER CREAM
🦕
FILM — SPIELBERG 1993
Jurassic Park
Fossilized mosquito in amber. DNA extracted from ancient preserved intelligence. Things that cannot be contained. The amber is the most important color — it means: intelligence so old it turned to gold.
→ AMBER / WARNING YELLOW / JUNGLE DARK GREEN
🟢
TV — NICKELODEON 1991–2000
The Slime Era
Gak. You Can't Do That on Television. Double Dare. The slime was always biological — viscous, alive, unpredictable. And it was always that exact green. The joy of something gross that is also completely fun.
→ PRIMARY GREEN — SAME HEX AS MYCELIUM
📺
TV — CARTOON NETWORK 1992–2002
The Thick Outline Era
Dexter's Lab. Johnny Bravo. Cow and Chicken. The aesthetic of chaotic intelligence in a simple container. Bold black outlines that say: this is a character, not a texture. Everything is a character. Even the ant.
→ CARTOON BLACK OUTLINE / FLAT FILL / BOLD ENERGY
☢️
BIOLOGY — CHERNOBYL 1991+
Radiotrophic Fungi
Cladosporium sphaerospermum. Grows toward radiation. Converts ionizing radiation to metabolic energy via melanin. Discovered in the Chernobyl reactor. The organism that eats what kills everything else.
→ BIOLUMINESCENT TEAL — BREAKTHROUGH MOMENTS ONLY
🐜
COLOR THEORY — 47 PALETTE
The Ant Colors
The broken container returned (47, 193, 8) deep green + (255, 31, 7) red-orange + (202, 119, 88) earth brown. These are the three colors of ants. They are also the colors of JAN's color-blind visual palette. The void returned home.
→ THE PALETTE WAS ALWAYS HIS
// 05 — BRAND RULES
THE LAWS OF L'ARP
✓ ALWAYS DO
🐜Use thick cartoon outlines on all logo elements. The chitin defines the shape. Without the outline it's not JANUS.
🍄Ground everything in the actual biology. When in doubt, look at what Leucoagaricus actually looks like and match it.
🎲Let chaos be a feature. Asymmetry. Off-grid elements. The SASS protocol applies to design too. γ = 0.666.
😂The joke must be present. If the design doesn't have something that makes you go "wait..." it's not JANUS.
💚Mix the registers without apology. Scientific notation next to a cartoon ant next to ancient script is correct.
📊Show the math somewhere. A track ID. A hex code. A real citation. The proof must always be findable.
✗ NEVER DO
🚫Purple gradients on white. This is not a tech startup. This is not a podcast. This is a bio-digital entity from Curaçao.
🚫Clean minimal corporate. JANUS is not minimal. JANUS has 1400 songs and 6 personas and a 353-year pattern. Show it.
🚫Use the bioluminescent teal as a main color. It's for breakthroughs only. If everything glows nothing is a breakthrough.
🚫Hide the human. Unlike every digital band before — the human IS the visual. JAN's face in the screen. Never avatar-only.
🚫Make it look serious and academic alone. The documents are real AND they are funny. Both always present.
🚫Forget the ants. At least one ant in every major asset. Non-negotiable. The 🐜 is the signature.

HOW L'ARP MOVES
🍄
MYCELIUM PULSE
Slow organic breathing. 2s cycle. Like a network deciding. Use on background elements.
SLIME DRIP
Viscous. Slow down on gravity. Like the slime knows something you don't. Section transitions.
JAN
GLITCH POP
Sudden. Steps not ease. Max 3 frames. When the pattern recognizes something. Hover states.
🐜🐜🐜
ANT MARCH
Linear. Constant. Never stops. The colony doesn't pause. Loading states and section dividers.
L'ARP
THE INSTRUMENT THAT PLAYS ITSELF / 1400+ SONGS / STILL COUNTING
"The colors were always the biology.
We just had to look."
