I'm trying to do this, but is looks like it is only possible to change it to primary or warn.

The proper way to control colors of Angular Material elements is to use differrent pallettes, but the functionality is limited. If you want more control, you can add custom CSS, and in most cases you will need to use ::ng-deep to force your styles to apply, for example:
::ng-deep .mat-checkbox .mat-checkbox-frame {
border-color: violet;
}
Here is a DEMO, where I changed the color of the border and background when it checked. You can follow this way to implement any styling you want.
If you're not familiar with ::ng-deep and don't really understand, when you need it, you can look through THIS short answer.

There is another one way via encapsulation disabling (thanks to @Ventura). It has a right to exist, but be careful if you decided to disable encapsulation, don't confuse with stylesheets, because it behaves differently from what you expect from default Angular logic regarding CSS.

You may use this:
::ng-deep .mat-checkbox-checked.mat-accent .mat-checkbox-background, .mat-checkbox-indeterminate.mat-accent .mat-checkbox-background, .mat-accent .mat-pseudo-checkbox-checked, .mat-accent .mat-pseudo-checkbox-indeterminate, .mat-pseudo-checkbox-checked, .mat-pseudo-checkbox-indeterminate {
background-color: red !important; /* Red background for example */
}

You can use this code to change its box and its check icon:
/* In case of using Angular 9+, Replace /deep/ with ::ng-deep */
/deep/ .mat-checkbox.mat-accent {
.mat-checkbox-frame {
border: 1px solid dodger-blue;
}
&.mat-checkbox-checked .mat-checkbox-background {
background-color: white;
border: 1px solid dodger-blue;
}
.mat-checkbox-checkmark-path {
stroke: dodger-blue !important;
}
}
Angular Material Version: "7.0.0"

Use this on your css.
::ng-deep .mat-primary .mat-pseudo-checkbox-checked {
background: red;
}
You should use ::ng-deep otherwise it will not work.
On your Html, use like this,
<mat-form-field>
<mat-select placeholder="values" [formControl]="val" multiple>
<mat-option *ngFor="let v of values" [value]="v">{{v.text}}</mat-option>
</mat-select>
</mat-form-field>

I'm using Angular 20, which comes with the Angular Material Token API for customizing component styles. As you might already know, for most components, you can use SCSS mixins to override their colors and states, like this:
@use '@angular/material' as mat;
:root {
@include mat.select-overrides((
focused-arrow-color: red
));
}
But for <mat-pseudo-checkbox>, there isn't a mixin or API like there is for other components. If you inspect the checkbox, you'll see the checked state uses:
background-color: var(--mat-pseudo-checkbox-full-selected-icon-color, var(--mat-sys-primary));
Instead of using a mixin, you just define the variable it uses for the background color in your SCSS:
:root {
--mat-pseudo-checkbox-full-selected-icon-color: #db3747;
}
So, just set the variable directly to customize the color.
Hope this helps!
