Hi Peter, The old thread where it was discussed is here:
I did by my own instructions and it worked quit well.
<style>
#Home_CHART_cards > md-card > md-input-container {
padding:0 !important;
margin:0 !important;
border-radius:20px;
background-color:var(--nr-dashboard-widgetColor);
}
#Home_CHART_cards > md-card > md-input-container > label{
position: relative;
top: 15px;
}
.nr-dashboard-theme .nr-dashboard-textinput input[type="color"]{
border: none !important;
width: 48px;
height: 48px;
margin: 0 !important;
padding: 10% !important;
}
</style>
of course the "Home_CHART_cards" must be changed to target correct tab and group
