Remove unnecessary step with number separator from Color function

AFAIK `object &= 0xFF_FF_FF;` was an unnecessary step, because

`object & 0xFF` is equivalent to `object & 0xFF_FF_FF & 0xFF` and
`(object >> 16) & 0xFF` is equivalent to `((object & 0xFF_FF_FF) >> 16) & 0xFF`

This should prevent the error described in https://github.com/Qix-/color/issues/204
