&a[0] is the same as just a.
As for the comment Michael had, for example a & ~0x03030303 after the shift would make the new code equivalent.
I am not sure what is correct, but I think a lot of other palette handling code has this same issue of giving weird results if there are more than 6 bits set in the palette variable.
I wonder whether all those shouldn't be using VGA palette and rotate the highest two bits in each byte in the lowest bit instead of shifting them up into the next component.
