Mondays car conversation

So on our way to Parker's preschool, this is what took place. Makenna is an up and coming driver. She always tells me when to go or to go faster. Now that she has learned that red means stop and green means go, this is the conversation she and Parker had......
Makenna: Mommy, go faster...green means go, go, go, mommy go!
Parker: Makenna, what does red mean?
Makenna: "Kar Kar" red means stop (with her hand up)
Parker: Makenna, what does yellow mean?
Makenna: SSSSLLLLOOOOWWWW DDDDOOOOWWWWNNNN
Makenna: "Kar Kar" orange means slow down too!
Parker: No it doesn't...there is no orange light (he was totally annoyed)

****Then, we drive through a new traffic light where the yellow looks orange*****

Makenna: See "Kar Kar" Orange means slow down! (her voice many decibles louder)
Parker: Oh

It was silent the rest of the way! By the way, How come my kids even saw the orange light, I thought orange means to slow down, not to go faster!
