How to set the color of an icon in Angular Material?

Question

I have this, which I would assume to work, but doesn't:

<mat-icon color="white">home</mat-icon>

Then, I also have:

<button mat-raised-button color="accent" type="submit"
 [disabled]="!recipientForm.form.valid">
    <mat-icon color="white">save</mat-icon>SAVE
</button>

This code snippet, for some reason, does work (shows the icon as white).

How do I get the lone mat-icon to show up as white using the color attribute? (I can easily just add a white class, but I want to understand this)

Answer 1

That's because the color input only accepts three attributes: "primary", "accent" or "warn". Hence, you'll have to style the icons the CSS way:

1. Add a class to style your icon:

   .white-icon {
       color: white;
   }
   /* Note: If you're using an SVG icon, you should make the class target the `<svg>` element */
   .white-icon svg {
       fill: white;
   }
   

2. Add the class to your icon:

   <mat-icon class="white-icon">menu</mat-icon>
   

Answer 2

In the component.css or app.css add Icon Color styles

.material-icons.color_green { color: #00FF00; }
.material-icons.color_white { color: #FFFFFF; }

In the component.html set the icon class

<mat-icon class="material-icons color_green">games</mat-icon>
<mat-icon class="material-icons color_white">cloud</mat-icon>

ng build

Answer 3

Or simply

add to your element

[ngStyle]="{'color': myVariableColor}"

eg

<mat-icon [ngStyle]="{'color': myVariableColor}">{{ getActivityIcon() }}</mat-icon>

Where color can be defined at another component etc

Answer 4

color="white" is not a known attribute to Angular Material.

color attribute can changed to primary, accent, and warn. as said in this doc

your icon inside button works because its parent class button has css class of color:white, or may be your color="accent" is white. check the developer tools to find it.

By default, icons will use the current font color
