## Docs
### cl.scales
All of the color scales in colorlover
```
>>> import colorlover as cl
>>> cl.scales['3']['div']['RdYlBu']
['rgb(252,141,89)', 'rgb(255,255,191)', 'rgb(145,191,219)']
```
### cl.to_numeric( scale )
Converts scale of RGB or HSL strings to list of tuples with RGB integer values
```
>>> cl.to_numeric( cl.scales['3']['div']['RdYlBu'] )
[(252.0, 141.0, 89.0), (255.0, 255.0, 191.0), (145.0, 191.0, 219.0)]
```
### cl.to_hsl( scale )
Converts a string RGB or numeric RGB colorscale to HSL
```
>>> cl.to_hsl( cl.scales['3']['div']['RdYlBu'] )
['hsl(19.0, 96.0%, 67.0%)', 'hsl(60.0, 100.0%, 87.0%)', 'hsl(203.0, 51.0%, 71.0%)']
```
### cl.to_rgb( scale )
Convert an HSL or numeric RGB color scale to string RGB color scale
```
>>> cl.to_rgb( cl.scales['3']['div']['RdYlBu'] )
['rgb(252,141,89)', 'rgb(255,255,191)', 'rgb(145,191,219)']
```
### cl.to_html( scale )
Traverse color scale dictionary and return available color scales as HTML string
```
>>> cl.to_html( cl.scales['3']['div']['RdYlBu'] )
'
'
```
### cl.flipper( scale=None )
Return the inverse of the color scale dictionary cl.scale
```
>>> cl.flipper()['div']['3']['RdYlBu']
['rgb(252,141,89)', 'rgb(255,255,191)', 'rgb(145,191,219)']
```
### cl.interp( scale, r )
def interp(scl, r):
Interpolate a color scale "scale" to a new one with length "r"
```
# fun usage in IPython notebook
from IPython.display import HTML
HTML( to_html( to_hsl( interp( cl.scales['11']['qual']['Paired'], 5000 ) ) ) )
```
## All colors in cl.scales
```
# (in IPython notebook)
from IPython.display import HTML
HTML(cl.to_html( cl.scales ))
```
