Regarding the image of purple rune items on https://www.tip.it/runescape/times/view/619-forever-runescape-part-2
Thought I should let you know that image is not legitimate. How do I know? I'm the one who created that image nearly 20 years ago for the RuneScape Wiki. I did the color sampling wrong which resulted in the items coming out more purple than they should be. The entire reason I made the image was a "what if" type of thing to show what a full set of purple runite gear would have looked like.
I am honestly surprised the image has survived this long, and even more surprised that it made its way onto this website at some point.
