Change color of underline input and label in Materialize.css framework

Question

I'm using the Materialize.css framework and I noticed that the color of the text input fields is green and so is the label.

Is there a way to change the color to something different?

<input type="text" id="username" />
<label for="username">Username</label>

Answer 1

You can, according to Materialize Docs by using:

 /* label focus color */
   .input-field input[type=text]:focus + label {
     color: #000;
}
/* label underline focus color */
   .input-field input[type=text]:focus {
     border-bottom: 1px solid #000;
     box-shadow: 0 1px 0 0 #000;
   }

The dippas answer is correct, but if you want textareas to be the same colour you have to set this CSS rules:

/* label focus color */
    .input-field input[type=text]:focus + label, .materialize-textarea:focus:not([readonly]) + label {
     color: #005eed !important;
    }

/* label underline focus color */
    .input-field input[type=text]:focus, .materialize-textarea:focus:not([readonly]) {
     border-bottom: 1px solid #005eed !important;
     box-shadow: 0 1px 0 0 #005eed !important;
    }

Note the .materialize-textarea rule for label and border bottom.

In case anyone is here in 2019 and trying this with the new version of Materialize (1.0.0) and not wanting to use !important in their css, the below snippet worked for me.

Note: This will apply to all input fields, if you want specific ones, i.e. text, then change [type] to [type=text].

    /* Inactive/Active Default input field color */
    .input-field input[type]:not([readonly]),
    .input-field input[type]:focus:not([readonly]),
    .input-field textarea:not([readonly]),
    .input-field textarea:focus:not([readonly]) {
        border-bottom: 1px solid #01579b;
        box-shadow: 0 1px 0 0 #01579b;
    }

    /* Inactive/Active Default input label color */
    .input-field input[type]:focus:not([readonly])+label,
    .input-field textarea:focus:not([readonly])+label {
        color: #01579b;
    }

    /* Active/Inactive Invalid input field colors */
    .input-field input[type].invalid,
    .input-field input[type].invalid:focus,
    .input-field textarea.invalid,
    .input-field textarea.invalid:focus {
        border-bottom: 1px solid #e57373;
        box-shadow: 0 1px 0 0 #e57373;
    }

    /* Active/Inactive Invalid input label color */
    .input-field input[type].invalid:focus+label,
    .input-field input[type].invalid~.helper-text::after,
    .input-field input[type].invalid:focus~.helper-text::after, 
    .input-field textarea.invalid:focus+label,
    .input-field textarea.invalid~.helper-text::after,
    .input-field textarea.invalid:focus~.helper-text::after {
        color: #e57373;
    }

    /* Active/Inactive Valid input field color */
    .input-field input[type].valid,
    .input-field input[type].valid:focus,
    .input-field textarea.valid,
    .input-field textarea.valid:focus {
        border-bottom: 1px solid #26a69a;
        box-shadow: 0 1px 0 0 #26a69a;
    }

    /* Active/Inactive Valid input label color */
    .input-field input[type].valid:focus+label,
    .input-field input[type].valid~.helper-text::after,
    .input-field input[type].valid:focus~.helper-text::after,
    .input-field textarea.valid:focus+label,
    .input-field textarea.valid~.helper-text::after,
    .input-field textarea.valid:focus~.helper-text::after {
        color: #26a69a;
    }
