Ich habe ein Control für meine Rolladen erstellt schaffe es aber nicht die auf und ab Pfeile der Material Icons einzufärben, Hindergrund geht. Ist das überhaupt möglich?

Hier mein Code:

<div id="root" @click='{"commands":[{"type":"ToggleSignalValue","signal":{"source":"propertry","name":"signalName"}}]}'>
    <span @click='{"commands":[{"type":"SetSignalValue","signal":{"source":"property","name":"auto"},"value":"toggle"}]}' bind-css:color='{"signal":"?automatik","converter":{"true":"#33d17a","false":"#e01b24"}}' style="grid-column:1 / span 3;grid-row:1;left:auto;top:auto;width:100%;color:[[?automatik]];">[[?this.name]]</span>
    <span bind-content:text="?status" style="grid-column:1 / span 3;grid-row:3;height:100%;left:auto;top:auto;width:100%;"></span>
    <img src="/icons-material-svg/navigation/ic_arrow_drop_up_48px.svg" @click='{"commands":[{"type":"SetSignalValue","signal":{"source":"property","name":"auf"},"value":""}]}' class="#008000" style="grid-column:1;grid-row:2;left:auto;vertical-align:bottom;width:53px;height:46px;top:auto;">
    <img src="/icons-material-svg/navigation/ic_arrow_drop_down_48px.svg" @click='{"commands":[{"type":"SetSignalValue","signal":{"source":"property","name":"zu"},"value":""}]}' style="grid-column:3;grid-row:2;left:auto;top:auto;width:44px;height:47px;">
    <img src="null" bind-prop:src='{"signal":"?status","converter":{"50%":"/icons-eclipse-smarthome-classic/svg/blinds-50.svg","0%":"/icons-eclipse-smarthome-classic/svg/blinds-0.svg","100%":"/icons-eclipse-smarthome-classic/svg/blinds-100.svg"}}' @click='{"commands":[{"type":"SetSignalValue","signal":{"source":"property","name":"stop"}}]}' style="grid-column:2;grid-row:2;">
</div>
