How to set color of toggle buttons

Question

I have group of toggle buttons. They are very light and disappear in the background on poor monitors with a high brightness level.

    border: 1px rgba(0,0,0,0) solid !important;
    margin-top: 5px !important;
    padding: 0 5px !important;
    z-index: 3 !important;
}

mat-button-toggle:hover {
    border: 1px #000 solid !important;
    background-color: #FFF !important;
    border-radius: 5px !important;
}

.mat-button-toggle-checked {
	  box-shadow: 0 0 30px #000 !important;
