```bash
# Check if terminal supports colors
tty-color --support
# Output: true

# Short form
tty-color -s
# Output: true

# Use in shell scripts for conditional coloring
if [ "$(tty-color -s)" = "true" ]; then
  echo -e "\033[32mColors are supported!\033[0m"
else
  echo "Colors are not supported"
fi
```

--------------------------------

### Check Terminal Color Mode

Source: https://context7.com/piotrmurach/tty-color-cli/llms.txt

Determines the maximum number of colors the terminal can display (e.g., 8, 16, 256, 16777216). Useful for selecting color palettes in scripts.

```bash
# Check number of supported colors
tty-color --mode
# Output: 256

# Short form
tty-color -m
# Output: 256

# Use in scripts to select appropriate color palette
COLORS=$(tty-color -m)
if [ "$COLORS" -ge 256 ]; then
  echo "Using 256-color palette"
elif [ "$COLORS" -ge 16 ]; then
  echo "Using 16-color palette"
else
  echo "Using basic 8-color palette"
fi
