    colors=["#FF0000", "#00FF00", "#0000FF"],  # Custom colors
    velocity=50.0,          # Fall speed

```python
from streamlit_effects import matrix_rain

# Simple usage
matrix_rain()

# Custom configuration
matrix_rain(
    duration=20,            # Effect duration (None = infinite)
    density="heavy",        # "light" (75), "medium" (150), "heavy" (240) columns
    speed=1.5,              # Fall speed multiplier (1.0 = 30s base)
    color="#00FF00",        # Classic Matrix green

**Note**: Matrix effect features 90-character columns with staggered starting positions, smooth fade-in, and English characters only for maximum readability.

## 🎯 Auto-Detection

Automatically apply seasonal and holiday effects based on the current date:

```python
from streamlit_effects import auto_effect

# Automatically detect and apply appropriate effect

## 📚 Complete Example

```python
import streamlit as st
from streamlit_effects import snow, confetti, auto_effect, get_season

st.set_page_config(page_title="My App", page_icon="🎨")

# Sidebar with season info
season = get_season()
st.sidebar.metric("Current Season", season.title())

# Auto-apply seasonal effect
if st.sidebar.checkbox("Enable Seasonal Effects", value=True):
    effect = auto_effect(intensity="medium")
    if effect:
        st.sidebar.success(f"✨ {effect} effect active")

# Main content
st.title("My Awesome Streamlit App 🚀")

# Manual effects
col1, col2, col3 = st.columns(3)

with col1:
    if st.button("❄️ Snow"):
        snow(intensity="heavy", duration=5)

with col2:
    if st.button("🎉 Confetti"):
        confetti(duration=3)

with col3:
    if st.button("🎆 Fireworks"):
        from streamlit_effects import fireworks
        fireworks(duration=8)

# Your app content here
st.write("Welcome to my app!")
```

## 🎛️ Advanced Usage

### Multiple Effects

Use unique `key` parameters to run multiple effects:

```python
from streamlit_effects import snow, confetti

# Both effects will run simultaneously
snow(key="background_snow")
confetti(duration=5, key="celebration_confetti")
```

### Conditional Effects

Apply effects based on app state:

```python
import streamlit as st
from streamlit_effects import fireworks, confetti

# Track user progress
if "tasks_completed" not in st.session_state:
    st.session_state.tasks_completed = 0

if st.button("Complete Task"):
    st.session_state.tasks_completed += 1
    
    # Confetti for each completion
    confetti(duration=2, key=f"task_{st.session_state.tasks_completed}")
    
    # Big fireworks at milestone
    if st.session_state.tasks_completed % 10 == 0:
        fireworks(duration=5, key="milestone")
        st.balloons()
```

### Custom Color Schemes

Create themed effects:

```python
from streamlit_effects import snow, floating_hearts

# Blue winter theme
snow(color="#A0D8F1", intensity="heavy")

# Valentine's theme
floating_hearts(
    colors=["#FF1493", "#FF69B4", "#FFB6C1"],
    intensity="heavy"
)

# Corporate colors
from streamlit_effects import confetti
confetti(
    colors=["#FF6B6B", "#4ECDC4", "#45B7D1"],  # Your brand colors
    particle_count=300
)
```
