Good catch! A color tuple will likely be used in '#%02x%02x%02x' % color, and 
this will fail because %x works only with integers (in general sense). 
Therefore returning a tuple of floats is a bug.

The downside is that we loss some information. Tk supports up to 16 bit per 
color component, and askcolor() keeps only higher 8 of them. This can't be 
changed for backward compatibility, but it may be worth to add an option for 
control the representation of the result. winfo_rgb() returns 16-bit color 
components. This is a separate issue.
