Tips for modifying the color of the input field in Ionic 5 upon receiving focus

Is there a way to change the color of an input field when it's focused? Currently, it turns grey only when focused by a function and remains so until typing or clicking on the field.

export function autofocus() {
    let blanks = document.querySelectorAll(".blank")
    let textfield = document.getElementById("textfield")

    if (blanks.length > 0) {
        document.querySelectorAll(".blank")[0].setFocus()
    }
    else if (textfield) {
        document.getElementById("textfield").setFocus()
    }
}

The responsible class is:

:host(.ion-focused) .item-native::after {
    background: var(--background-focused);
    opacity: var(--background-focused-opacity);
}

Unfortunately, this is part of the Shadow DOM. Does anyone know how to solve this issue? The opacity should ideally be set to zero.
