emacs -Q
Eval this: (defcustom foo "Red" "..." :type 'color)
 
M-x set-variable foo RET Blue RET
 
gives error "Value `Blue' does not match type color of foo". Likewise,
if I try BlueViolet.
 
M-x customize-option foo
 
Empty the value field and hit M-TAB. The colors are displayed in a
crazy order, not alphabetically. And there is no color `Blue' in the
list. But you can enter the text `Blue' anyway and choose Set for
Session from the menu. So the completion must be lax, which is
good. 
 
But why does `set-variable' say that `Blue' does not match type
`color'? And it says the same thing for `BlueViolet', which is one of
the names available using completion in Customize.
 
And `set-variable' too should offer completion (enhancement request).

You want to do

  M-x set-variable foo RET "Blue" RET

because set-variable reads entries in Lisp form, and foo needs to be a
string.

They are listed in the same order of list-colors-display.  I've changed
that to make it alphabetical.
