Changing default css in Angular Material for md-input - angularjs

Question

I have implemented form using angualr-material, I can't find any standard ways to change default color coding in material.
form
<div class="col-xs-12 testFormLabel">
<md-input-container class="testLabel">
<label>Reason</label>
<input name="reasonBox" id="reasonBox" ng-model="obj. reasonBox" ng-required="true">
</md-input-container>
</div>
css
.md-input-has-value. testLabel > input {
color:#008cba;
}
Problem
How can i change auto focus label name and underline to different color ( let say from dark blue to green )

Answer 1

You can use this selector to change the input:
md-input-container:not(.md-input-invalid).md-input-focused .md-input {
border-color: red
}
Use this to change the label:
md-input-container:not(.md-input-invalid).md-input-focused label {
color: red
}
Include this after you include the css for angular material.
I got this by going to the docs page here: https://material.angularjs.org/latest/demo/input
Looking at their demo, and inspecting a focused input.

You can also use <md-input-container [dividerColor]="primary|accent|warn"> to set the color when the field is in focus.
From the docs...
The divider (line under the input content) color can be changed by using the dividerColor attribute of md-input-container. A value of primary is the default and will correspond to the theme primary color. Alternatively, accent or warn can be specified to use the theme's accent or warn color.
