How do I change the color of an md-icon in Angular Material?

Question

I started to use Angular Material in my project and I was wondering how I can change the svg color inside an am-button.

This is my code:

<md-button class="md-fab md-primary">
    <md-icon
        class="ng-scope ng-isolate-scope md-default-theme"
        style="height: 14px; width: 14px;"
        md-svg-src="img/material-icons/core/arrow-forward.svg"
    ></md-icon>
</md-button>

What do I need to add to change the color of the svg from the curent black to white, just like in Google's button demo? (section "Icon button using Font-icons")

Answer 1

The SVG is under the md-icon, so you could add this to your style:

md-icon {
  color: red
}

md-icon svg {
  fill: inherit;
}

Answer 2

I was having a similar problem, I needed to change the SVG color using CSS, but I also needed to keep the original SVG color (e.g. fill="#fff") when no CSS was supplied.

I enhanced Jason Aunkst's approach to make it work. Here's the solution:

md-icon[style*="color:"] svg [fill] {
    fill: inherit;
}

That class will set any svg's child element with a fill attribute to inherit the color value as long as the svg is a child of an md-icon element that contains the style attribute with a color value.

It will only work on SVG's that are only using one fill color though. Adjust as needed, hope it helps!

Easiest way out

Now there's no need to change the svg or the fill property.

Simply add the !important to md-icon's color property in CSS:

md-icon {
  color: #FFF !important;
}

Answer 4

For the people trying to color their md-icon, I found out that I had the same problem using Angular 1.3.x and Angular Material 0.8.x.

I fixed the problem by editing my SVG files and deleting the "fill" attribute that was overriding any inherited color.

After deleting this "fill" attribute in each SVG file, I could properly choose the color I wanted to assign to the icon thanks to CSS as specified by Jason Aunkst.

Add this to your css:

svg {
    fill: inherit;
}

The svg will now inherit the fill attribute of your md-icon

<md-icon style="fill: red;" md-svg-src='/img/ic_menu_white_24px.svg'></md-icon>

Answer 6

Am using this in the CSS :

.my-icon svg
{
   fill : #fff;
}

And in the HTML :

<ng-md-icon icon="search" class="my-icon"></ng-md-icon>

Works fine!

Answer 7

One way to do it is by setting a custom class selector.

HTML:

<md-button class="md-fab mybtnstyle">
  <md-icon md-svg-src="img/icons/cake.svg"></md-icon>
</md-button>

CSS:

.md-button.md-fab.mybtnstyle {
  background-color: blue;
}

.md-button.md-fab.mybtnstyle:hover {
  background-color: red;
}

The issue seems to be with the downloaded SVGs from Google Design icons as they override the fill attribute in the svg root. Compare the view source of SVGs on Google Design with the ones used in the example.

Solution:: Override fill in css.

md-icon svg {
    fill: currentColor;
}

Answer 9

The following is the only way I've gotten it to work via stylesheets.

md-icon {
  svg {
    path {
      fill: #ffffff;
    }
  }
}

I'm on angular-material 0.8, and I simply added

    style="color:white;font:bold;" 

to the md-icon element.

I was having a similar problem when trying to change default svg icon color. For those who are experiencing the similar issue, make sure you check the angular-material version you're currently using. Currently, I'm using the angular-material "0.7.1" and this is quietly important.

NOTE: with my current Angular-material (0.7.1) version, the <mdIcon></mdIcon> directive only checks to see if attr.Icon is defined or not during postLinking compileFunction. With this implementation, in order to reference your svg icon files, you simply add icon attribute to your <mdIcon icon="iconsDir/path_to_icon_file.svg"></mdIcon> element directive. Notice in the earlier angular-material version, you might have use md-src-svg for referencing your svg files, its no longer the case in 0.7.1 version.

So if you were using 0.7.1 and following above instruction, you should have your svg icon rendering correctly, now its time to change the background-color of the svg you're using.

Raw svg file before any modification:

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" x="0px" y="0px" width="24px"
 height="24px" viewBox="0 0 24 24">
<g>
    <path d="M6,2C4.9,2,4,2.9,4,4l0,16c0,1.1,0.9,2,2,2h12c1.1,0,2-0.9,2-2V8l-6-6H6z M13,9V3.5L18.5,9H13z" />
</g>

You should have a folder within your project where you save all your svg icons, in my case, I have a folder named icons where I store all my svg icons. The example svg file above is the non-modified svg icon where I got it from https://github.com/google/material-design-icons. (Default its rendering as a black svg file)

To change the default svg file, you would simple add a fill attribute to your raw svg file. See modified svg file version:

<path d="M6,2C4.9,2,4,2.9,4,4l0,16c0,1.1,0.9,2,2,2h12c1.1,0,2-0.9,2-2V8l-6-6H6z M13,9V3.5L18.5,9H13z" fill="green" />

I simply added fill="green" the path element svg file, and now my svg icon is rendering as color green instead of default black. I know some of you guys might be using a different version of angular-material, but the mechanism of changing default svg color should apply the same. Hopefully this can be helpful to solve your problems, thanks!

You should be able to do this by add "fill:white" to the style of the icon.

<md-icon class="ng-scope ng-isolate-scope md-default-theme" style="height: 14px; width: 14px; fill:white" md-svg-src="img/material-icons/core/arrow-forward.svg"></md-icon>
