DOES NEXUS 5 YELLOW COLOR SHOW SOMETHING ABOUT ANDROID L!

Previously we saw android L being confirmed for Moto g and Moto x here but this time this is more interesting. Earlier on the play store it was noted that grab your nexus 5 of multi color but when people used to click on that link only a red color nexus was spotted which indicated the exact color of Kitkat but this time the yellow one appeared.
Does this indicate the name of andrroid L? It could be lemonaide or lemmon pop or anything like that. So are you guys ready for the suprise behind it or you know something else? please comment and thanks for response @ItsTechForYou
