In htop, color codes are used to visually represent different types of resource usage and process states. Here’s a breakdown of the common color codes you might encounter:
CPU Usage
- Green: Represents the percentage of CPU time spent on user processes.
- Red: Indicates the percentage of CPU time spent on system (kernel) processes.
- Blue: Shows the percentage of CPU time spent on low-priority processes (nice).
- Orange: Represents the percentage of CPU time spent on I/O wait.
Memory Usage
- Green: Indicates used memory.
- Blue: Represents buffer memory.
- Yellow: Shows cache memory.
- Red: Indicates swap memory usage.
Process States
- Green: Running processes.

Example Interpretation
When you open htop, you might see a colorful bar graph at the top representing CPU usage. Each color segment helps you quickly identify how much of your CPU is being used by user processes, system processes, and others.
