Favorite shade of blue:Probably this one
Something about this exact crayon absolutely entranced me as a kid. It's bright, but not too bright, and with just a touch of green, but only slightly...and so rich... I loved it. I still love it. Closely followed by the color of cobalt glass. I'm really funny about blues, though- they have to be pretty exact. I love cobalt, but hate royal. I also really like labradorite but I'm pretty sure that doesn't count as a single color.
