Is there any list of color names that can be used for the labels in survey123? is there any way to use custom colors, like put the HEX code or the RGB numbers? egg. <font color="navy"><b>example</font>. Thank you.
If Survey123 follows standards (which I suppose it does) you should be able to use any of these HTML Color Names
Xander is correct.
A few examples are
<span style="color:#f58a1f">orange</span>
<font color="red">Text in red </font>
