# Effekte schreiben
```python=1
import time
def effect( lp ):
lp.clear( )
x = 4
color = ( 255, 0, 0 )
lp.set_pixel( 0, x, color )
lp.show( )
time.sleep( 2 )
```
----
# color
* 3-Tuple mit int8: `( 0, 0, 255 )`
* String mit hexadezimaler Notation: `"d511ff"`
----
# lp = Lightpipe()
```python
lp.set_pixel( p, x, color )
lp.set_pipe( p, color )
lp.fill( p, x, colors )
lp.clear( show, background )
lp.show( )
```
----
## Alles mit Unter-Pixel
```python
lp.set_pixel_0( p, x, color )
lp.set_pixel_y( p, x, color, y )
lp.fill_0( p, x, colors )
lp.fill_y( p, x, colors, y )
```

# paintbag.pb
```python
pb.colors_37c3
pb.random_color( )
pb.cgs( color1, color2, n )
```
----
# Hübscher Effekt
```python=1
import time
def effect( lp, pb ):
color_a = pb.random_color( )
color_b = pb.random_color( )
gradient = pb.cgs( color_a, color_b, lp.p_size )
lp.fill( 0, 0, gradient )
lp.show( )
time.sleep( 5 )
