It isn't possible for color inputs to suffer from a type mismatch,
because the spec says "User agents must not allow the user to set the
value to a string that is not a valid lowercase simple color."  If the
user somehow selects an invalid color, the UA is required to simply
refuse it, or auto-correct it somehow.  This doesn't work well with a
text input, where the user has to type the color incrementally -- I
guess the UA could decide to not update the script-visible/submitted
value until the user no longer focuses the form field, and if the
value isn't valid at that time, it could revert to the previous value.
