[0.17.69] Compilatron messages - coal icon is hard to see

[bjorntfn]

Very early in the introduction / arrival level, Compilatron asks the player to Insert Coal into the stone furnace.

The coal icon is obscured by the effect applied to Compilatron's chat with the player. Snip attached.
This is distracting while the effect is running, and makes the icon hard to see and inconsistent with its appearance in other UIs.
(It looks a bit more like Iron than Coal in my opinion)

Thanks for the report. Fixed for version 0.17.76.
I switched it to use the special on-dark-background version of the coal icon, so it should be more legible.
