If today is your birthday, then yes, you do. XD

Birthdays... there's another one every day.

So today is for everybody to enjoy their unbirthday? Let's celebrate everyday! WE MUST NOW BLOW THE CANDLES OF WISHING AND EAT THE CAKE OF BIRTHING TO CELEBRATE THIS JOYOUS OCCASION.

*cuts cake and passes pieces out to everyone* XD Its a rainbow cake. :3

So this cake is made of the rainbow? But I thought rainbow wasn't tangible... *GASP* Are you.... A genie?

I WISH I KNEW WHAT I WANTED TO WISH FOR!

Nope, just know how to use food coloring. XD
CAKE~

I thought you made rainbow cake with dissolved gelatin flavors?

Unbirthday is overrated. There should be a "lifeday", which is everyday!

Then lets celebrate the life of everyday!
HURRAH!

@Witchy
If its a white cake you can also dye it, just note that it will look paler depending on how much dye you used. (my real mom has dyed a cake blue, or at least tried to, she added in red and it made it more purple than blue ^^; )

*noms on her cake*
WOOT! Its awesome to be alive! XD

Why did you show me that picture?!?
My boyfriend's niece's birthday part is next Saturday, and now I have this NEED to make her a rainbow cake...

lol, Sorry Solar, I'd blame it on the awesomeness of a rainbow cake. XD

Try Jello of rainbow instead:

Easier it is, cake is hard.

That looks yummy too, sadly though I'm not fond of jell-o. x'D

But, but, but... ain't nobody don't like parfait!
