Ruby, Generate a random hex color (only light colors)

Question

I know this is possible duplicated question. Ruby, Generate a random hex color

My question is slightly different. I need to know, how to generate the random hex lig

Answer 1

I modified one of the answers from the linked question (Daniel Spiewak's answer) to come up with something that is pretty flexible in terms of excluding darker colors:

floor = 22 # meaning darkest possible color is #222222
r = (rand(256-floor) + floor).to_s 16
g = (rand(256-floor) + floor).to_s 16
b = (rand(256-floor) + floor).to_s 16

[r,g,b].map {|h| h.rjust 2, '0'}.join

You can change the floor value to suit your needs. A higher value will limit the output to lighter colors, and a lower value will allow darker colors.
