## Visual Design System

### Colors (Subtle, Not Bold)
```python
# OLD: Bold, saturated colors
accent_color = "\033[1;35m"      # Bright magenta
success_color = "\033[1;32m"     # Bright green
error_color = "\033[1;31m"       # Bright red

# NEW: Subtle, muted colors
accent_color = "\033[38;5;103m"  # Soft purple
success_color = "\033[38;5;108m" # Muted green
error_color = "\033[38;5;131m"   # Soft red
muted_color = "\033[38;5;245m"   # Gray for subtle text
```

### Spacing
```python
# OLD: Compact
padding = 0
line_height = 1

# NEW: Breathable
padding = 1   # One space padding
line_height = 1.5  # More vertical space
```

### Borders
```python
# OLD: Box drawing
border = "┌─┐│└┘"

# NEW: Simple lines or none
border = "─"  # Just horizontal separators
# OR no border at all, use whitespace
```

### Focus Indicators
```python
# OLD: Cursor arrows, bright backgrounds
cursor = "▶ "
background = "\033[7m"  # Inverted video

# NEW: Subtle background tint
focus_bg = "\033[48;5;236m"  # Light gray background
# OR just underline
focus_underline = "\033[4m"
```

## Example Code Pattern

### OLD Style:
```python
def render(self):
    lines = [
        f"{self.colors.accent_color}┌─{'─'*width}─┐{self.colors.reset}",
        f"{self.colors.accent_color}│{self.colors.reset} {content} │",
        f"{self.colors.accent_color}└─{'─'*width}─┘{self.colors.reset}"
    ]
    return lines
```

### NEW Style:
```python
def render(self):
    lines = [
        "",  # Blank line for spacing
        f"{self.colors.muted_color}{'─'*width}{self.colors.reset}",
        f"",  # Spacing
        f"  {content}",  # Indented content
        f"",  # Spacing
        f"{self.colors.muted_color}{'─'*width}{self.colors.reset}"
    ]
    return lines
```
