I was responding to your blanket assertion that "black means evil and white means divine in popular culture", which is clearly not true as I've illustrated. Colors have various connotations depending on the context, you have simply latched on to one context and want to apply it everywhere to fit your argument. The fact that AMEX chose to brand their ultra-exclusive card as AMEX Black is telling. Clearly, AMEX thinks you are going to associate their card's name with luxury and exclusivity, and aren't going to associate their card with evil.
