>>10366953Yep, that's what happens when you add white to lighten a colour. Same if you add black to darken it. White and black are both basically just the extreme ends of the grey scale, so adding them to another colour will pull that colour towards the greyscale. Or to put it in more technical terms: white and black both have zero saturation (just like pure greys), so anything you mix them into will have its saturation decreased. Likewise maximum saturation is only possible in the middle of the brightness scale, while the extreme ends of it only exist at zero saturation (ie black and white).
A pale tan won't be quite as desaturating if the colour you add it to isn't on the opposite end of the colour wheel hue-wise, but it's still damn close to white and so it will still desaturate most things a fair bit too. To make a brighter green of equal saturation you're going to need a brighter equally saturated green to mix in (though obviously that too can only get you so far, but since we're looking at camouflage here our desired end result is unlikely to hit the absolute limit of saturation for your desired brightness).
