# I have this string:
# 
# Color1  R=144 G=248 B=255
# 
# Need regular expression for get R,G,B
# How I can simplify it:
# 
# lines.gsub!(/Color1  R=(\d+) G=(\d+) B=(\d+)/) {
#       puts $1
#       puts $2
#       puts $3
# }

irb(main):026:0> s = "Color1  R=144 G=248 B=255"
=> "Color1  R=144 G=248 B=255"
irb(main):030:0> r,g,b=(/R=(\d+)\s+G=(\d+)\s+B=(\d+)/).match(s).captures
=> ["144", "248", "255"]
irb(main):031:0> r
=> "144"
irb(main):032:0> g
=> "248"
irb(main):033:0> b
=> "255"
