color not being set for workspace button subclasses

[VJMReichenbach]

I am trying to change the color property of the active and urgent workspace buttons. Changing the background-color works, the color however stays the same. Here is my config:

* {
    font-family: FiraCode Nerd Font Mono;
    font-size: 18px;
    color: #cdd6f4;
    border: none;
    border-radius: 20px;
}

window#waybar {
    background: rgba(0, 0, 0, 0);
}

/*-----module groups----*/
.modules-right {
    margin: 2px 10px 0 0;
}
.modules-center {
    margin: 2px 0 0 0;
}
.modules-left {
    background-color: rgba(30, 30, 46, 0.7);
    margin: 2px 0 0 5px;
}
/*-----modules indv----*/

/* button:hover { */
/*     background-color: #313244; */
/* } */

#window,
#workspaces {
    margin: 0 4px;
}

#workspaces button {
    padding: 2px 9px;
    color: #cdd6f4;
}

#workspaces button.active {
    color: #f5c2e7;
}

#workspaces button.urgent {
    color: #1e1e2e;
    background-color: #f38ba8;
}

#pulseaudio:hover {
    background-color: #313244;

It seems that the text in #workspaces button is actually in #workspaces button label, e.g., this works for me:

#workspaces button label {
	color: red;
}
