Putty is great. Putty's default color scheme is not. But you can change the default color scheme. It is a big pain in the ass but you can do it. Or you can run a reg file like the one below to do it for you.
1) Create a text file profile-theme.reg
2) Update the contents to the contents below (replace with your theme name).
3) Save and Run the file. If get a UAC prompt, grant the permission to run the file.
*4) If you want to update the Default theme, set the theme name to "[HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions\Default%20Settings]"
