Convert string to color hash

So it happens that sometimes you need to convert string to color hash. I think that Digest::MD5 class is easiest way for this. For this you need call hexdigest method with necessary string.

Digest::MD5.hexdigest('My string')[0..5] # => 'a537d0'

And if you will create rgb color you need convert hex to decimal with to_i(16) method.

  .map{ |color| color.to_i(16) }
