XP Mode with 32 bit color + integration is possible!
I found an easier way to get 24 bit colors with integration on here.
1. Run regedit in XP.
2. Navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services].
3. Add a DWORD Value named "ColorDepth" w/o parenthesis.
4. Right-click it, modify, then put "4" in the Value data.
5. Restart XP mode / Reboot
