What exactly do the colors in htop status bars mean?

Hitting F1 or h will show you the key. But for reference, the default colors are:

CPU:

  • Blue = Low priority threads
  • Green = Normal priority threads
  • Red = Kernel threads

Memory:

  • Green = Used memory
  • Blue = Buffers
  • Yellow/Orange = Cache

There are a couple of different color-schemes available, you can see them through hitting F2.
