This is as simple as.
Red= Strongly Disagree
Orange= Just Disagree
Yellow= More Disagree than Agree
Green= Neutral on the subject
Light Blue= More Agree than Disagree
Blue= Just Agree
Purple= Strongly Agree
Someone will comment on a subject, lets take Euthanasia for example, and others will reply with a colour that corresponds to their view.
Oh, added to that, a comment or reason for the colour is always nice.
YOU HEARD THAT.
WELL, YOU BETTER GET STARTED NOW!
And, to be completely unimaginative, why don't we with Euthanasia.
