My vim color theme file is my_black.vim, the background color of the vimc window is set to black in my_black.vim the code is as follows: set background=dark I am using the xshell emulation terminal, and its current color scheme is set to "New black", the background color of this color scheme uses a dark gray instead of black. What does " ^[[4%p1%dm" mean? What color does it represent? I saw the value of the t_AB option by using the " set termcap" command: t_AB=^[[4%p1%dm

If I want to set the background color of vim in the terminal, which set of options should I use? I use vim in a terminal that its type is linux. Why are there three sets of options, what is the difference between them? T_8b set background color (R, G, B) *t_8b* *'t_8b'* T_8f set foreground color (R, G, B) *t_8f* *'t_8f'* T_RB request terminal background color *t_RB* *'t_RB'* The third set of options: t_RF request terminal foreground color *t_RF* *'t_RF'* T_Sf set foreground color *t_Sf* *'t_Sf'* The second set of options: t_Sb set background color *t_Sb* *'t_Sb'*

T_AF set foreground color (ANSI) *t_AF* *'t_AF'* The first set of options: t_AB set background color (ANSI) *t_AB* *'t_AB'* I see three sets of options for terminal colors on the vim documentation.
