@angular/pwa: Consider necessity of defaulting to the specific theme-color #1976d2

[Yves-X]

Command

add

Description

When running ng add @angular/pwa to set up the Angular service worker, Angular CLI automatically adds a <meta name="theme-color" content="#1976d2"> tag to index.html.

The choice of this specific color (#1976d2) seems pointless. Is there a particular reason for this default?

Additionally, this behavior feels inconsistent with Angular CLI's typical approach of generating neutral templates. For instance, the CLI doesn't set a default lang attribute in HTML and expect developers to modify it; instead, it leaves this tag unset by default.

Describe the solution you'd like

I’d suggest one of the following:

• Remove the default <meta name="theme-color"> from the schematic.
• Replace the color with a neutral default.
• Make the additional option via a prompt when running ng add @angular/pwa.

Describe alternatives you've considered

Developers can manually change or remove the tag when reviewing changes or after noticing unexpected UI coloring.
However, since theme-color affects the browser UI rather than visible page elements, it can be difficult for less experienced developers to pick the color and trace its source.
