Actually, they should be invisible, since they should look like you do. Currently, you look invisible. This makes them largely useless, at least until you attack. Unless, of course, you are proposing ...
What does "look invisible" mean?
It means you look like what is behind you, correct?
If what is behind the caster is purple, an image should be purple too. It should not be blue, just because what is behind the image is blue.
The image emulates the appearance of the caster, it does not emulate the appearance of what is behind the image.
Invisibility is not an appearance.
And if you rule that the caster does not have an appearance when invisible, well the total lack of appearance would be black.

Yeah, it looks like you are.
What happens when a caster casts Mirror Image and then casts Polymorph or Alter Self to change his appearance? How about if the caster puts on a non-magical disguise? How about a magical disguise? Do his Mirror Images remain the same? Or do they change to reflect the new form?
What if the caster had cast the appearance altering spells, donned the diguise, etc., before casting Mirror Image?
What happens when the caster is hit with a Dispel Magic that strips the Alter Self / Polymorph effect, but not the Mirror Image?
At all times, as per the Mirror Image spell, the image looks, acts, and sounds like the caster.
If the caster looks like polka dots because he is standing in front of a polka dot door, then the images should look that way too, regardless of whether they are in front of the door. Plus, since they are moving, their polka dots should move as well.

In short, it seems like your ruling is unnecessarily complicated and weakens the spell more than its worth.
Complicated?
To tell you the truth, I do not care which of the two ways it works. As long as the rules support that.
The rules (as written) really do not support the other interpretation.
The Blur, Displacement, and Invisibility spells target the caster and their effects work on the caster.
They do not target the Mirror Image images.
And, Mirror Image states that it gains the appearance of the caster. It does not state that it gains any special game mechanics of that appearance.
I would be ok with Mirror Image doing as the Sage stated in the FAQ as long as the Mirror Image spell itself (or the errata on it) said so.
From a purely game mechanics point of view, Mirror Image does not state that the images gain any benefits of other magic that the caster has on him, so they shouldn't gain benefits.
It's as simple as that.
Mage Armor spell targeted on caster. Mirror Image images do not get it.
Protection From Arrows spell targeted on caster. Mirror Image images do not get it.
Etc., etc., etc.
Here is a question for those who think that illusion spells should not conflict with each other.
What happens when a Wizard with Mirror Image up casts Mislead?
1) The images blink out because the actual caster goes invisible. This would indicate to a knowlegable person that Mislead was cast and the seen Wizard is not the real wizard. Hence, a conflict of illusions.
2) The images show what is behind the caster and move with him. This would indicate to a knowlegable person that Mislead was cast and the seen Wizard is not the real wizard and that the real Wizard is near those quasi-invisible images. Hence, a conflict of illusions.
3) The images blink out, but Mislead creates new images for the new illusion of the Wizard. This seems beyond the power of Mislead to create a single figment.
But in order to avoid the "conflict of illusions" issue, you have to give Mislead more power than the spell states it has. Just like you have to have Blur effectively target the Mirror Images, or have Mirror Images gain the benefits of some of the targets personal spells and not the benefits of other personal spells.
