Where he says "light olive" he is miles off and has ignored the part of the design sheet that tells you the colors are for pattern measurement only and to refer to the official color chips. The design sheets are water colors, semi-accurate as in the color is in the correct family but does not match exactly the hue, chroma or value and often you can see where the camoufleur literally dipped their brush in water to stretch out the current color and the shade changes. Also the version he uses is from a web posting and has been significantly tweaked from the grungy, duller original, yep had it in my hands ate one time.

Olive No.2 is MUCH darker. Very close out of the bottle match Tamiya XF-67 NATO Green, I could probably get closer but it's already an almost perfect match. Yes I do know what Olive No.2 and most of the WWI dazzle colors were because I Munsell matched the extant color chips at NARA, mixed my own chips, compared, tweaked, lathered, rinsed, repeated until I had them nailed.
