Who doesn't love blue? The color of trust, the color of mood, the theme of a favorite Joni Mitchell song. A scientifically proven boost for creativity. Blue is also the color that brings the Internet to its knees. How? You can do a lot of amazing things online, but one thing you can't ever do is International Klein Blue (IKB). That "pure energy" ultramarine color, invented by the French artist Yves Klein in 1960, requires a matte synthetic resin binder to preserve and promote the color's intensity. I amped the blue in this graphic shot of red tree buds, but I still couldn't photoshop my way to IKB. It's material. It's texture. It's layered. Like nature, IKB doesn't live online. The other day I counted sixteen people near me in a subway car. All of them were glued or tethered to their phones. I hope they get a chance to walk outside unplugged.
