Yogurt for breakfast....which color is best?

Ben came to me this morning, "Want a yogurt, Ninnie, want a yogurt."
I got up to get him one. he follows me, "Want a blue one." (Blueberry flavor that is)
"Okay....we'll see. I think all the blue ones are gone. Would a pink one be okay?" (Strawberry)
"Want a blue one."
"But if there isn't one, would a pink one be fine?"
"Pink one."

I get downstairs...
"Red one! Actually want a red one." (re-defining strawberry's color)
There was a blue one.
"Have a blue one!!" Ben said with a HUGE smile.
