@tbsbdr needs a concept/decision regarding "focus color" and "background color for currently selected element in OcSelect"

[tbsbdr]

I'd suggest a two-color indicator so that the contrast of the focus is always high regardless of its background. It must not look ultra-nice, it must be clearly recognisable while eg. tabbing https://www.w3.org/WAI/WCAG21/Techniques/css/C40#example-1-a-thick-two-color-indicator

*:focus {
    /* inner indicator */
    outline: 2px #F9F9F9 solid;
    outline-offset: 0;
    /* outer indicator */
    box-shadow: 0 0 0 4px #193146;
}
