Try setting the truecolor option with lolcat --truecolor or lolcat -t.

[rashil2000]

It works with --truecolor, but I wonder why it behaves differently by default?

[j4james]

Looking at the source, I think lolcat checks the COLORTERM environment variable. So if you set that to truecolor, it'll probably select the truecolor option automatically. I'm guessing Xfce sets the COLORTERM variable itself.

Ah, thanks for the detailed answer! Since WT doesn't have a way to set env vars (I believe #9287 is still under review), I'll make a user-wide entry in the Start Menu -> Environment Variables for COLORTERM.
Should I close this then?

[j4james]

Yeah. If you're happy that your issue has been addressed - or will be addressed by #9287 - then you can probably close.
