I want to find out what are the default colors of a 3D bar chart in Showroom layout on keynote. When you add a new chart, you get this colors: enter image description here

But I was unable to find them in the colors palette.


I had a look at the internals of a fresh Showroom layout Keynote file (it's a zipped folder actually). Inside, there is a index.apxl file which contains lots of data .. also color data. I wrote this short Ruby script to make a quick-and-dirty html file with all colors used in the Keynote document:

#!/usr/bin/env ruby

puts "<!DOCTYPE html><html lang=\"en-us\"><body>"
file = IO.read("index.apxl") # slurp apxl file

# iterate through file and convert color info to 8-bit integer:
file.scan(/sfa:[rgb]=\"(\d\.?\d*)\"\s+sfa:[rgb]=\"(\d\.?\d*)\"\s+sfa:[rgb]=\"(\d\.?\d*)\"/) do |w|

  r = (w[0].to_f*255).to_i
  g = (w[1].to_f*255).to_i
  b = (w[2].to_f*255).to_i
  puts "<div style=\"width:100px;height:100px;float:left;background:rgb(#{r}, #{g}, #{b});\">&nbsp;</div>"

puts "</body></html>" # close html

After pruning duplicate lines, this is the visual result of the process.

These colors are used in the default Showroom layout. You can now select (one click) the individual same-colored areas of a bar graph (here: grey or red).

In the graphics inspector (graphics inspector) you can change the colors according to your wishes. Pick the colors from above graphic with the color picker like this:
