Runny noses - what colour means what

My yard owners mare has greeny colour gunk outside her stable every morning if she doesnt wet her hay, the dust really effects her x
 
my mare has copd and if theres alot of hay/straw about i quite often find a whitey/yellowy discharge type gunk on the floor, vets said this was nothing to worry about!
hope this was some help! R
