Navy Blue, Yellow, and red
BLUE
Egg Blue goes with many colors but my two favorites are a dark purple or a light and sparkly silver....
Silver
chocolate brown or duck egg blue
Sort of a sky blue color, but sometimes they may lay white eggs.
A Crow???
If it is a small egg and depending on where it was found it is probably a tit egg ( most common being blue tit)
To mock them.
the counting crows sung colour blind
Purple is a cold colour.. and my favourite!
Yes There Is. They look like ordinary crows but there white and there beak and feet is a pink-ish colour. They also have red eyes
