Colour guide

After brosing the Montana website, looking at the various brandings for different types of spray paint, I came across their online .pdf version of a colur guide. I want to find some physical examples of colour guides to look at how they work with regards to print, but in terms of layout, colour names and range, these are definitly a good starting point. I'll be looking at other examples from different companies to gain a wider understanding of what I'll be producing.
