I feel quite desperate for a Light Mode/Dark Mode toggle in the Survey123 field app. My technicians use my surveys in a variety of outdoor conditions and times of day, and though I have done my best to come up with a color palette for our surveys that fits all prevailing conditions, I am still constantly asked to provide an inverse-able option. I don't think this currently exists in Survey123, at least not in the field app.
I envision a tweak to the front-end survey design tools in Survey123 Connect. One could input a survey style setting similar to 'pages' or 'grid', etc., called 'Palette Inverse Toggle' (or something) to be 'true' or 'false'; if set to true, they then have the option of defining two color palettes for the survey instead of one. If it isn't obvious, one would be the 'dark' mode and one would be the 'light' mode. For surveys with the palette toggle enabled, the end-user of the survey would simply have a slider button in either the survey header or the footer (I think header makes more sense) that allows them to easily switch between the two palettes.
Apologies if this feature exists and I don't know about it (please illuminate me!). I absolutely DO NOT want to have to double the amount of surveys I manage simply to invert the color palette of all my existing ones.
