Hospitals use color codes to quickly communicate important information about different areas, personnel, and situations. Understanding what these color codes mean can help patients, visitors and staff navigate the hospital more easily. The main color codes used in hospitals are for floors, departments, scrub uniforms, linens, emergency codes, gases, waste and hazardous materials. Each color has a specific meaning and helps provide visual cues in the complex, fast-paced hospital environment.
Floor Colors
| Color | Meaning |
|---|---|
| Red | Labor and delivery floor |
| Blue | Newborn nursery floor |
| Yellow | Pediatrics floor |
| Pink | Maternity and obstetrics floor |
| Green | Surgery floor |
Hospitals often color code floors by department. For example, the labor and delivery floor is usually red, the newborn nursery floor is blue, the pediatrics floor is yellow, the maternity and obstetrics floor is pink, and the surgery floor is green. This color coding helps patients, visitors and staff quickly locate the correct floor for their needs. The vivid colors also help make wayfinding easier in busy hospitals.
Department Colors
| Color | Department |
|---|---|
| Navy blue | Cardiology |
| Orange | Pharmacy |
| Purple | Dialysis |
| Yellow | Physical therapy |
| Brown | Radiology |
Specific hospital departments are also assigned designated colors. For example, cardiology departments often use navy blue, pharmacies are orange, dialysis units are purple, physical therapy is yellow, and radiology is brown. These consistent colors allow patients and visitors to easily identify different departments throughout the hospital. The colors are used on signs, nurse uniforms and floor lines in larger hospitals.
Scrub Color Codes
| Color | Personnel |
|---|---|
| Royal blue | Surgeons, anesthesiologists, nurse anesthetists |
| Ceil blue | Medical students, interns |
| Green | Surgery nurses, surgical technologists |
| Lavender | Licensed vocational or practical nurses |
| Yellow | Nursing assistants, hospital housekeepers, patient care technicians |
Hospital scrubs also follow a color coding system to identify personnel. Surgeons, anesthesiologists and nurse anesthetists wear royal blue scrubs. Medical students and interns wear ceil blue. Surgery nurses and surgical technologists wear green. Licensed vocational or practical nurses wear lavender. Nursing assistants, hospital housekeepers and patient care techs wear yellow. Knowing who wears each color helps patients understand the roles of hospital staff caring for them.
Linen Colors
| Color | Meaning |
|---|---|
| Red | Isolation linens |
| Blue | Cardiology linens |
| Green | Surgical linens |

| Brown | Orthopedics linens |
Hospitals also use color coding for linens such as sheets, pillowcases, blankets and towels. Red linens indicate isolation. Blue is for cardiology departments. Green designates surgical linens. Yellow is used for pediatrics. Brown linens are for orthopedics patients. The color coding helps hospital staff efficiently find the right linens and return them to the correct department after laundering. It also assists with infection control.
Emergency Code Colors
| Color | Code Type |
|---|---|
| Red | Fire |
| Orange | Hazardous spill |
| Yellow | Bomb threat |
| Blue | Medical emergency – adult |
| Pink | Medical emergency – infant |
| Purple | Child abduction |
| Green | Evacuation |
| White | Violent situation |
| Gray | Severe weather |
Hospitals have emergency color codes to communicate different situations that require immediate attention and response. Code red signals fire. Code orange is a hazardous material spill. Code yellow is a bomb threat. Code blue indicates a medical emergency involving an adult patient. Code pink is a medical emergency involving an infant patient. Code purple means a child abduction from the pediatric unit. Code green is used to initiate evacuation procedures. Code white alerts staff to a violent situation. Code gray warns of severe weather requiring safety precautions.
Gas Cylinder Colors
| Color | Gas Type |
|---|---|
| Green | Oxygen |
| Blue | Nitrous oxide |
| Yellow | Helium |
| Red | CO2 |
| Gray | Nitrogen |
| Magenta | Ethylene oxide |
Gas cylinders in hospitals also follow a color coding system. Green cylinders contain oxygen. Blue is for nitrous oxide gas. Yellow cylinders hold helium. Red is for carbon dioxide. Gray cylinders contain nitrogen. Magenta designates ethylene oxide gas cylinders. This color system allows hospital staff to quickly identify and handle each gas appropriately. Proper gas cylinder storage and handling is critical for hospital safety.
Medical Waste Colors
| Color | Waste Type |
|---|---|
| Red | Infectious waste |
| Orange | Hazardous pharmaceutical waste |
| Brown | Regular trash |
| Yellow | Radioactive waste |
| Black | Chemical waste |
| Green | Recyclable materials |
Hospitals classify waste into different color coded categories for safe disposal. Red bags or containers hold infectious waste. Orange is for hazardous pharmaceutical materials. Regular trash goes into brown containers. Radioactive waste is in yellow. Chemical waste goes into black bags or boxes. Green containers are for general recyclable materials like paper and plastic. Following color coding protocols in waste disposal helps ensure hazardous hospital waste is handled appropriately.
