Weird, looks like something in the IPS responsive theme is force-overriding the colour attribute.
I have a workaround and have just uploaded v1.3.1 to fix it. Thanks for reporting it!
NOTE: I discovered that on a recent enough Android device, because emoji have fixed colours, you may be unable to override the colour of a snowflake that is an emoji, such as ❄. In this case, I recommend using a different, non-emoji character as your snowflake, such as • instead.
