Got a good eye for the redheads?

Yesterday we rounded up 22 famous gingers in preparation for Redhead Day. Today we up the ante and make it a little harder for you: here are 23 jaw-dropping pictures from our photo library, but the catch is they're not all true redheads.

Can YOU spot the dye jobs? Click on to try.

1) We'll make the first one easy for you

There's no hiding when the ginger is this strong within you. We're just amazed she can go out in the sun.

Now that you know what to look for, let's spot an easy fake...

2) Beautiful...but not a real redhead

This exceedingly lovely lassie might have smiling Irish eyes, but she's no ginger. That's a brunette with style.

Now get ready, because it's going to get harder for you...

3) Be our redheaded girlfriend?

Real or fake, this gal's the marrying kind

4) Devil in a Blue Dress

Red-hots like this lady make even cool colors boil

5) If that's fake, we don't want to try real

That woman doesn't have hair; she has molten bronze

6) Instagram ginger

This redhead's got sleeve tattoos, so you'll have a lot harder time finding the telltale freckles

7) Leather and light

You're going to have to guess hard here...

Although she makes hard easy to do.

8) Fine, we'll give you a better look

Just to hedge your bet.

9) What does this redhead know?

Because she either has a secret, or just figured out one.

10) No, you cannot offer us a drink

It speaks to the power of redheads that there are basically four sections of this photo composition, and alcohol is the least attention-grabbing of any of them.

Besides, we don't want blue right now. We're only seeing red.

11) Stay focused!

You're not going to be able to tell by the hair alone. Eyes up and see if her face gives you any clues.

12) Again with the blue...

Redheads--Hasn't anyone told you that you absolutely kill in green?

Probably because then Christmas comes early.

13) The XXX-Files

Tell us she doesn't look like tomorrow she'll be playing Scully in The X-Files porn parody.

It's cool if you disagree, man. We trust your opinion, since you've watched way more porn than anybody else we know.

14) Because we love you

We thought you deserved to see this gal in her entirety, adorable tummy and all.

She's aces, that one.

15) Tough call, easy decision

If that's a dye job, she wears it well enough to deserve a deputy redhead badge

16) Beret-wearing redhead mocks your best guess

But appreciates your admiration!

17) This one's a little on-the-nose

But so was that pun.

18) Fantasy redhead

Honestly, this woman doesn't exist outside of photosessions. There's no Italian shore where she stands in the breeze and waits for you to pour her expensive wine.

But if she were real, would she be a redhead?

19) Peek-a-boo

What's up, real life Jessica Rabbit?

20) Noir

What, no purse with a snubnose .38 in it?

21) All these redheads defy you

They're just sure you're going to guess wrong...

...which sort of betrays which ones are real, doesn't it?

22) We're speechless

23) Hey, it's her again

Looks like she's figured out who her ginger sisters are, and who's an infiltrator.
