Well I have stayed at mostly Renaissance hotels-and they are not true green-but usually some khaki variation,
The full serivice Marriots have some sort of "regal"pattern(only stayed on C'floors-just by luck mot by status)either green or blue.
courtyard(palm springs)and FairfieldInn(anaheim hills)a true-and truly ugly green.
I am getting ready to install new carpet in my home and I am leaning toward commercial/hospitality grade carpet for duribilty and ease of cleaning,so I will be paying more attention.
