I print this icon into a table using php code like this:
echo '<button Onclick="" style="border: none; background: none; color:green"><a title="Reenviar" data-toggle="tooltip"><i class="material-icons"></i></a></button>';
And I'd ike to change the icon's color. I tried to add the color to the button style; however it does not seem to work.
You should add style to i tag
<i style = "color:blue;" class="material-icons"></i>
also, you can create a css class
.blue {
color:blue
}
and then just add that class to a tag
<i class="material-icons blue"></i>
