Angular material design - how to add custom button color?

问题

I want to add my own custom colors, similar to "primary", "warn" etc. For example, I added a class for an orange background, but I use it as a class and not as a color attribute. It works, but the code looks a bit confusing.

<button md-raised-button
        color="primary"
        class="btn-w-md ml-3 orange-500-bg">
          <i class="material-icons">description</i>
          Deactivate
</button>

What do I need to do to add it as color="orange"?

回答1:

You can change the color of the button only in the normal css way by defining a class for background color orange and using it as class attribute.

If you need to use it as color="orange". Then you need to create your own theme with the colors you need. Refer Theming your angular material app on how to do it. You can even make it custom for each element. Through customisation you can choose different themes based on elements

But still you wont be able to use it like color="orange", you can define orange as your primary or accent color and use it as color="primary" or color="accent" based on your need.

Theme can have only following items with different colors

A primary palette: colors most widely used across all screens and components.
An accent palette: colors used for the floating action button and interactive elements.
A warn palette: colors used to convey error state.
A foreground palette: colors for text and icons.
A background palette: colors used for element backgrounds.

You can add any color like below

 <a mat-mini-fab color="success" routerLink=".">link</a>

it generates the class with that value like 'mat-success' then create css for that class

.mat-success {
    background-color: green;
    color: #fff;
}

I have created styles for all mat-button types

STACKBLITZ DEMO

(add to your global styles)

.mat-button.mat-success,
.mat-stroked-button.mat-success {
    color: #155724;
}
.mat-button.mat-success:hover,
.mat-stroked-button.mat-success:hover {
  background-color: #f0fff3;
}

.mat-raised-button.mat-success,
.mat-flat-button.mat-success,
.mat-fab.mat-success,
.mat-mini-fab.mat-success {
  color: #f0fff3;
  background-color: #155724;
}

.mat-icon-button.mat-success {
  color:#155724;
}

Using a stylesheet at the referenced at component level

.mat-button, .mat-raised-button{
    background-color:red;
}

Note: Declare the stylesheet reference at the component level. LIVE DEMO

This answer is in the context of an angular 5.1.1 project using angular/cli and angular material 5.1.

The mat-... seems to inherit its color from the parent so if you surround with a span or div and apply the color there it should fall through. In my particular use case we wanted to dynamically set the color of icons. Our initial implementation and new implementation are below.

This class assignment will override the mat-icon class. It appears that this use to work but does not anymore:

<mat-icon [class]="custom-class">icon name</mat-icon>

Now you can wrap:

<span [class]="custom-class"><mat-icon>icon name</mat-icon></span>

The first case lead to the words "icon name" colored as desired but no icon. The second case lead to the desired behavior.

you can use a class with background

example:-

CSS:-

.save-button {
  background: green;
}

HTML:-

<button mat-mini-fab class="save-button" >
       <mat-icon >save</mat-icon>
</button>

Because the template checker gives an error/warning when you are using custom colors, there is a hacky way around it. This is only for the real desperate people who like things to be strict strict strict and have proper hinting from the IDE :)

First step is to create your own ambient declaration. I've added mine to the polyfills.ts, because I'm a bit lazy:

declare module '@angular/material/core/common-behaviors/color' {
  interface CanColor {
    // @ts-ignore
    color: CustomThemePalette;
  }
}

The @ts-ignore is necessary, otherwise you'll get the following error:

TS2717: Subsequent property declarations must have the same type. Property 'color' must be of type 'ThemePalette', but here has type 'CustomThemePalette'.

Then you can define your custom theme palette:

import type { ThemePalette } from '@angular/material/core/common-behaviors/color';

export type CustomThemePalette = ThemePalette | 'secondary' | 'success' | 'alert';

Now finally you can use those custom colors in your template, and your IDE will hint them and notify you when you've mistyped them. Victory!

_{note: obviously things will go south this way, when material decides to change their CanColor interface or move it around, but I suppose it would be relatively easy to adapt to such changes}
