Comment (Including rationale for any proposed change):
\"Note 4: ... white is assumed.\"



May be worth mentioning that users could have set their own bg colour as well.

\"Note 4: ... white is assumed. However, it\'s worth noting that users may have set their own preferred background color, which may differ considerably from the luminance value of white.\" or similar
