I use fastfetch and not neofetch.
This is bottom of my ~/.bashrc
fastfetch --logo-padding-left 1 --logo-padding-right 0 --logo-padding-top 1 --key-padding-left 1 -l ~/Pictures/Logos/OMLogoBR300.png
You may have to tweak the padding depending on the font size. That logo is 300x300 and I have one that is 100x100 for the kicker logo. the 100x100 has a lot more red border, so it shows up when small.
The rest of Konsole matches the colors of the logo, due to the om-colors theme. New entries in OpenMandriva repositories - #54 by WilsonPhillips
