This is maybe a bug, or maybe I am just doing something wrong.
When I set the theme, my survey looks as shown here:

I expect setting the theme colors to affect the text for all the questions in the survey.
Set custom theme colors, as shown in the examples. The theme I am trying to set is a "dark" theme. Some of the questions have the light text and dark background I set, but many still have their default colors. Also, the dropdown ends up with light text _and_ a light background.
Test code
let themeColors = Survey.StylesManager.ThemeColors['default'];
themeColors["$main-color"] = palette.primary.main;
themeColors["$main-hover-color"] = palette.primary.dark;
themeColors["$text-color"] = palette.text.primary;
themeColors["$header-color"] = palette.secondary.main;
themeColors["$border-color"] = palette.divider;
themeColors["$header-background-color"] = palette.secondary.main;
themeColors["$body-background-color"] = palette.background.default;
themeColors["$body-container-background-color"] = palette.background.paper;
themeColors["$inputs-background-color"] = palette.background.paper;
themeColors["$error-color"] = palette.error.main;
themeColors["$error-background-color"] = palette.error.light;
Survey.StylesManager.applyTheme('default');
My palette contains the following:

Thank you for the reporting! I've fixed the bug. Fix will be available in the next minor update.
Very similar question but not sure it would be fixed in your existing bug fix. So, just in case: I have the exact code @awlayton has to set the default theme colors. However, take a look at the border of the textbox in the attached image. It's supposed to be the main color, which I've set to orange. However, the default green main-color is overriding it.

@Aadmaa it should be fixed by the commit above.
Could you please check the example with the latest build: https://plnkr.co/edit/PzcCjxhFRKcVw5v4heRQ?p=preview and if you find any bugs please let me know.
Thanks.
That looks right. Thanks!
It's much better now, however the inputs still do not all have the same text color. My understanding is my theme should make all of the text white, but some is still a shade of grey.

@awlayton looks like a bug for me. I will check it tomorrow. Thank you.
@awlayton I've fixed the problem. Fix will be available in the next minor release. And I updated the plunker above https://plnkr.co/edit/PzcCjxhFRKcVw5v4heRQ?p=preview
