Pantone Color Cue
Color snobs will just eat up Pantones new “Color Cue“–which can identify any color in 3 seconds. It gives you Pantone color ink formulas and CMYK, Adobe RGB, sRGB, HTML, Hexachrome and a slew of other incredibly nerdy ways to say “This shirt is salmon not pink”, when you’re arguing with your friends. The Color Cue is a bit pricey at $239, but this is a hell of a lot of information to fit in the palm of your hand.
