Why does `ansi-color-names-vector' appear in my .emacs?

Why does `ansi-color-names-vector' appear in my .emacs?

[Xue Fuqiao]

I found this expression in my .emacs:

  (custom-set-variables
  [...]
   '(ansi-color-names-vector
     ["#2d3743" "#ff4242" "#74af68" "#dbdb95" "#34cae2" "#008b8b"
"#00ede1" "#e1e1e0"])
  [...])

I don't know why this expression appears in my .emacs, I'm sure I have
never customized this variable directly.  I have searched it in the
manuals and web, but I still don't know what these colors are for and
how this expression was generated.  Can anyone point me in the right
direction?

In general, anything inside custom-set-variables is generated by
"M-x customize-variable RET".

I have a question: can the Emacs's customize interface ensure the variables
only be evaluated once? I guess that the answer is probably not, but is
there any way to achieve that goal while keep the original `defcustom'
expression unchanged?

Thanks.

Thanks for your attention.  But I haven't set this variable manually,
the only customization regarding color I customized is this expression:

     '(custom-enabled-themes (quote (tsdh-dark)))

After I changed the Emacs theme, the a-c-n-v variable is automatically
modified.  Why?

How would I know?  Perhaps the theme invokes Customize behind the
scenes.  Look at the code.
