I use dark themed slack and

:melty-flame:

[melty flame] blends too much with the dark background, hence I've added

:melty-flame-border:

[ melty flame border ]. Unfortunately not find a good image asset for

:melty:

[ melty ] and

:melty-rainbow-flame:

[ melty rainbow flame ] , hence if someone has a good good quality png files laying around, please share and I can do the same border on those too..
