Change the default color of materialize.css input fields. I have attached screenshot - materialize

Question

I have tried to add custom css, but not worked. I need to change the color of text after selecting the input fields.
<div class="input-field form-group">
<input id="first_name" class="active validate form-control" name="first_name" type="text" value="">
<label for="first_name" class="mat-label">First Name</label>
</div>

Answer 1

An easier way, though you should edit the SCSS files.
But if you want in quick then use the following css.
I have used royalblue color here, you can use any hex color.
For bottom border
input:focus {
border-bottom: 1px solid royalblue !important;
box-shadow: 0 1px 0 0 royalblue !important;
}
For label color
label.active {
color: royalblue !important;
}

For the line color, I was able to change the default green to black with the css below.
input:not([type]):focus:not([readonly]), input[type="text"]:not(.browser-default):focus:not([readonly]), input[type="password"]:not(.browser-default):focus:not([readonly]), input[type="email"]:not(.browser-default):focus:not([readonly]), input[type="url"]:not(.browser-default):focus:not([readonly]), input[type="time"]:not(.browser-default):focus:not([readonly]), input[type="date"]:not(.browser-default):focus:not([readonly]), input[type="datetime"]:not(.browser-default):focus:not([readonly]), input[type="datetime-local"]:not(.browser-default):focus:not([readonly]), input[type="tel"]:not(.browser-default):focus:not([readonly]), input[type="number"]:not(.browser-default):focus:not([readonly]), input[type="search"]:not(.browser-default):focus:not([readonly]), textarea.materialize-textarea:focus:not([readonly]) {
border-bottom: 1px solid black;
-webkit-box-shadow: 0 1px 0 0 black;
box-shadow: 0 1px 0 0 black;
}

Answer 3

This green is actually $secondary-color
So in SASS, here is how it can be changed:
$secondary-color: #FEBD09;
#import "materialize-css/sass/components/variables";

Answer 4

When using Sass, you can change the color scheme of your site
extremely quickly.
To change the style of input/form you will only have to modify the variables under 10. Forms:
https://github.com/Dogfalo/materialize/blob/master/sass/components/_variables.scss
After changing the values, you need to build the new CSS file using SASS command line

Answer 5

You can change the text color easily by changing the code like
<div class="input-field form-group">
<input id="first_name" class="active validate form-control" name="first_name" type="text" value="">
<label for="first_name" class="mat-label">
<span class="black-text">First Name</span>
</label>
</div>
That is append -text to the color class. Check : http://materializecss.com/color.html

This is the CSS, you can change colors of materialize input animated text
input:not([type]):focus:not([readonly])+label,.form-wrap input[type=text]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=password]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=email]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=url]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=time]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=date]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=datetime]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=datetime-local]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=tel]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=number]:not(.browser-default):focus:not([readonly])+label,.form-wrap input[type=search]:not(.browser-default):focus:not([readonly])+label,.form-wrap textarea.materialize-textarea:focus:not([readonly])+label{

}
.form-wrap input:focus:not([type]):not([readonly]),.form-wrap input[type="text"]:focus:not(.browser-default):not([readonly]),.form-wrap input[type="password"]:focus:not(.browser-default):not([readonly]), input[type="email"]:focus:not(.browser-default):not([readonly]),.form-wrap input[type="url"]:focus:not(.browser-default):not([readonly]), input[type="time"]:focus:not(.browser-default):not([readonly]),.form-wrap input[type="date"]:focus:not(.browser-default):not([readonly]), input[type="datetime"]:focus:not(.browser-default):not([readonly]),.form-wrap input[type="datetime-local"]:focus:not(.browser-default):not([readonly]), input[type="tel"]:focus:not(.browser-default):not([readonly]),.form-wrap input[type="number"]:focus:not(.browser-default):not([readonly]), input[type="search"]:focus:not(.browser-default):not([readonly]),.form-wrap textarea.materialize-textarea:focus:not([readonly]){
