i have built this app https://cvirus.app and build and deployed on browser.
on chrome browser on android phones it renders dark background (as dark theme is being applied by default it seems).
I want to force light theme everywhere no matter what device what browser. how do I do that?
commenting dark colors portins in theme/variables.scss did not work
Since version 79 of the Chrome browser, you can choose between CSS prefers-color-sheme media feature values. Ionic respects this media feature and reacts to changes to it.
To change it without changing your OS preference and color theme, you need to open the Rendering panel in the Chrome Dev Tools:
Drawer | Show rendering selected, which should be already selected.The Rendering drawer opens. Then on the "Emulate CSS media..." option, select the color scheme you prefer.
To resolve this, you have to go to theme/variable.scss at the src folder and locate
@media (prefers-color-scheme: dark)
And change from dark to light. If you have not modified the variable.scss. it should be in line 79. Click to see the screenshot of my own code I hope this helps.
you should comment ios body and md body classes at the theme/variables.scss then it will become light mode.
In ionic 5+ Just rename prefers-color-scheme: dark to prefers-color-scheme: light Then It will not switch to dark theme no matter what.
In my case, commenting the dark theme in theme/variables.scss works well.
I comment on line 70 @media (prefers-color-scheme: dark) {

Hope to help you
One way to do this is to force light styles by using media queries. On devices that prefer light, you can supply your dark theme variables, but you need to override @media (prefers-color-scheme: dark) scope with your light theme variables.
One way to do this is to use a mixin for your theme, and include it in both :root scope and @media (prefers-color-scheme: dark).
Conversely, if you want to force dark theme, use a mixin for your theme, and include it in both :root scope and @media (prefers-color-scheme: light).
Note: Ionic (ionic/cli@6.10.0) and SCSS
/**
* {@mixin} - Supplies dark theme variables to the included scope
*/
@mixin eternal-darkness() {
// Dark theme variables...
}
:root {
@include eternal-darkness;
}
@media (prefers-color-scheme: light) {
@include eternal-darkness;
}
In my web browser, the theme was light. Which is what I wanted.
In the ios emulator, it was dark. To make it light I did this:
In variables.css
@media (prefers-color-scheme: lights) {
...
}
Simply have this tag placed in index.html file
<meta name="color-scheme" content="light dark" />
It works for me! Thanks
