Nosy can change colour at will, though this was more an involuntary response to the all-pervading gloominess in the Hub. Being empathic has its downsides.

It started out russet with green patches - camouflage among the bracken before it was found. It turned green so it wouldn't get stepped on in the Hub, turned red for Red Nose(y) day, and now it's got the blues.

Thank you!
