Providing a dark viewing mode while preserving formatting

A method for improving visibility of content displayed in a graphical user interface while preserving original content formatting comprising:

• receiving content for displaying on the graphical user interface;
• parsing the received content into one or more objects;
• comparing, for at least one of the one or more objects, a first characteristic of the at least one of the one or more objects with a reference characteristic to determine if a contrast between the first characteristic and the reference characteristic satisfies a first contrast ratio threshold requirement;
• upon determining that the first contrast ratio threshold requirement is not satisfied, adjusting the first characteristic;
• comparing, for the at least one of the one or more objects, a second characteristic of the at least one of the one or more objects with the adjusted first characteristic to determine if the contrast between the adjusted first characteristic and the second characteristic satisfies a second contrast ratio threshold requirement;
• upon determining that the second contrast ratio threshold requirement is not satisfied, adjusting the second characteristic;
• providing the at least one of the one or more objects with the adjusted first characteristic and the adjusted second characteristic for being displayed on the graphical user interface;
• and
• providing a plurality of options on a graphical user interface to be displayed on the display screen for toggling display of the content between an original received content version and a second content version displayed having adjusted color characteristics, each of the plurality of options toggling the display of content between the original received content version and the second content version on one of a plurality of regions of the graphical user interface;
• wherein at least one of the first contrast ratio threshold requirement or the second contrast ratio requirement is variable for different text sizes.

A non-transitory computer readable medium on which are stored instructions that, when executed, cause a programmable device to:

• receive content for displaying on a display screen;
• parse the received content into one or more objects, based on a formatting of the one or more objects;
• compare for at least one of the one or more objects a first characteristic of the at least one of the one or more objects with a second characteristic to determine if a contrast between the first characteristic and the second characteristic satisfies a contrast ratio threshold requirement;
• upon determining that the contrast ratio threshold requirement is satisfied, adjust the first characteristic;
• provide the at least one of the one or more objects with the adjusted first characteristic for being displayed on the display screen;
• and
• provide a plurality of options on a graphical user interface to be displayed on the display screen for toggling display of the content between an original received content version and a second content version displayed having adjusted color characteristics, each of the plurality of options toggling the display of content between the original received content version and the second content version on one of a plurality of regions of the graphical user interface,
• wherein the contrast ratio threshold requirement is variable for different text sizes.
