You can change the floating label color of the TextBox for both success and warning validation states by applying the following CSS styles.
/* For Success state */
.e-float-input.e-success label.e-float-text,
.e-float-input.e-success input:focus ~ label.e-float-text,
.e-float-input.e-success input:valid ~ label.e-float-text {
color: #22b24b;
}
/* For Warning state */
.e-float-input.e-warning label.e-float-text,
.e-float-input.e-warning input:focus ~ label.e-float-text,
.e-float-input.e-warning input:valid ~ label.e-float-text {
color: #ffca1c;
