Ruby, Generate a random hex color

Question

How can I generate a random hex color with ruby?

Answer 1

SecureRandom.hex(3)
#=> "fef912"

The SecureRandom module is part of Ruby's standard library

require 'securerandom'

It's autoloaded in Rails, but if you're using Rails 3.0 or lower, you'll need to use

ActiveSupport::SecureRandom.hex(3)
