Hi Fernando,
Thanks for confirming, that's very helpful.
Since you're on RDM 2026.2.17.0 with a DVLS workspace and the entry type is the native SSH Shell, here's what's happening.
The SSH Shell entry never launches putty.exe, it has its own built-in terminal. So the installation path configured under Settings > Application > Paths > PuTTY, and any colorization set only inside putty.exe itself, have no effect on it.
The fix in the topic you referenced (implemented in RDM 2024.3) only applies at the moment you use the "Convert Putty to SSH Terminal Session" action on an existing PuTTY entry. At that point, the color configuration from the PuTTY entry is copied once into the resulting SSH Shell entry's Terminal > Display > Colors. Since your session was already an SSH Shell entry and wasn't created through that conversion, that copy never happened, so the colors were never applied.
To get the same colors you see in putty.exe, you have two options depending on scope:
For this specific session only: open the entry's Properties > Terminal > Display, set Colors to Override, and enter the same values you configured in PuTTY's Window > Colours.
For all your SSH sessions: go to File > Settings > Entry types > Sessions > Terminal > Colors, set Override mode, and enter the values there. This applies globally, and you can also use the Import/Export buttons on that screen if you want to save or share the color scheme.
Either way it's a manual match, but it's a one-time setup and it will look identical to your PuTTY session going forward.
Best regards,
