if you try to change color of FAB by using app, there some problem.
frame of button have different color, so what you must to do:

<pre><code>app:backgroundTint="@android:color/transparent"

and in code set the color:

<pre><code>actionButton.setBackgroundTintList(ColorStateList.valueOf(getResources().getColor(R.color.white)));

The point we are missing is that before you set the color on the button, it's important to work on the value you want for this color. So you can go to values > color. You will find the default ones, but you can also create colors by copping and pasting them, changing the colors and names. Then... when you go to change the color of the floating button (in activity_main), you can choose the one you have created 

Exemple - code on values > colors with default colors + 3 more colors I've created:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;resources&gt;
 &lt;color name="colorPrimary"&gt;#3F51B5&lt;/color&gt;
 &lt;color name="colorPrimaryDark"&gt;#303F9F&lt;/color&gt;
 &lt;color name="colorAccent"&gt;#FF4081&lt;/color&gt;

 &lt;color name="corBotaoFoto"&gt;#f52411&lt;/color&gt;
 &lt;color name="corPar"&gt;#8e8f93&lt;/color&gt;
 &lt;color name="corImpar"&gt;#494848&lt;/color&gt;

&lt;/resources&gt;
</code></pre>

Now my Floating Action Button with the color I've created and named "corPar":

<pre><code>&lt;android.support.design.widget.FloatingActionButton
 android:id="@+id/fab"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="bottom|end"
 android:layout_margin="@dimen/fab_margin"
 android:src="@android:drawable/ic_input_add"
 android:tint="#ffffff"
 app:backgroundTint="@color/corPar"/&gt;

It worked for me. Good Luck!

 app:fabSize="mini"
 app:layout_anchorGravity="end|bottom|center" /&gt;



&lt;/androidx.coordinatorlayout.widget.CoordinatorLayout&gt;

</code></pre>

I have been trying to change Material's Floating Action Button color, but without success.

<pre><code>&lt;android.support.design.widget.FloatingActionButton
 android:id="@+id/profile_edit_fab"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="end|bottom"
 android:layout_margin="16dp"
 android:clickable="true"
 android:src="@drawable/ic_mode_edit_white_24dp" /&gt;
</code></pre>

I have tried to add:

<pre><code>android:background="@color/mycolor"
</code></pre>

or via code:

<pre><code>FloatingActionButton fab = (FloatingActionButton) rootView.findViewById(R.id.profile_edit_fab);
fab.setBackgroundColor(Color.parseColor("#mycolor"));
</code></pre>

or

<pre><code>fab.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#mycolor")));
</code></pre>

But none of the above worked. I have also tried the solutions in the proposed duplicate question, but none of them works; the button remained green and also became a square.

P.S. It would be also nice to know how to add ripple effect, couldn't understand that either.
