Change angular material input style

Question

I am trying to change the style of a angular material input.

So far I managed to change the background-color using :

md-input-container {
    padding-bottom: 5px;
    background-color: #222;
}

The placeholder and label color using :

md-input-container.md-default-theme label,   
md-input-container.md-default-theme .md-placeholder {  
    color: #FDFE67 !important; 
} 

But I can't manage to change the line color under the text when we focus the input and the text color when we type in the input.

Here is the html input :

<md-content>
    <md-input-container>
        <label>{{isEnglish ? 'Search...' : 'Recherche...'}}</label>
           <input ng-model="searchInput" id="sInput" 
                  ng-change="filterCartoList(searchInput)" my-enter="filterCartoList(searchInput)">
    </md-input-container>
</md-content>

Edit: I managed to change the text color when typing this way :

md-input-container .md-input {
color: rgba(255,255,255,0.87);
border-color: rgba(254,253,103,0.82);
}

Answer 1

<md-input-container style="position: relative; top:19px;">
                              <label style="border-color: white; color: white;">Email</label>
                              <input style="border-color: white; color: white;" >
                              </md-input-container>

Answer 2

This is the CSS selector used by Angular Material:

md-input-container:not(.md-input-invalid).md-input-focused .md-input {
    border-color: your_color_here;
}
