## DESCRIPTION

### Color groups are groups of species (genes, experiments, ..). Every species can only belong to ONE color group.

### All species of one color group are displayed in the same color in the tree display.

## NOTES

### The colors used to display can be customized with 'Properties/Tree: Color and fonts/Edit color groups'

### It's possible to toggle between marks and colors using 'ARB_NTREE/Species/Colors'
