Summary email bg color not changing when hex

Hi! I have a self-hosted discourse install and I’m trying to edit the colors for the digest email.

If I change email accent bg color to a color name (ex. “blue”), the color change shows up correctly in the preview. However, if I change the email accent bg color to a hexadecimal code, it doesn’t work.

I suspect the issue might be that the field won’t let me type # in front of the numbers/letters for the hex code. If I reset the color to the original hex code (#2F70AC), then the # is included and that color will display properly.

Please let me know if I’m missing something here or if this is a bug.
