custom type `color' is not enforced

[Drew Adams]

emacs -Q

(defcustom foo "White" "xxxxxxx" :type (quote color))

M-x customize-variable foo

In Customize, change the value to "any-non-color-string". You are able
to set the new value and even save it. There is no check done that the
value is actually a color - any string will do. The value should be
checked to ensure that it matches either a defined color name or "#"
followed by a multiple of three hex digits (for RGB).
