How do I convert a hex triplet to an RGB tuple and back?

Question

I\'d like to convert a hex triplet to an RGB tuple and then convert a tuple to a hex triplet.

Answer 1

Here you go. I use it to convert color to graphviz color format in #RGBA format with prefix=#.

def rgba_hex( color, prefix = '0x' ):
    if len( color ) == 3:
       color = color + (255,)
    hexColor = prefix + ''.join( [ '%02x' % x for x in color ] )
    return hexColor

USAGE:

In [3]: rgba_hex( (222, 100, 34) )
Out[3]: '0xde6422ff'

In [4]: rgba_hex( (0,255,255) )
Out[4]: '0x00ffffff'

In [5]: rgba_hex( (0,255,255,0) )
Out[5]: '0x00ffff00'
