Keith's eye color
in paint.net using dropper on his eye from the close-up face shot on here gives an RGB value of 70,70,98 for the lighter part and an RGB value of 23,23,39 for the darker part. the hue of this color is 240, which is solidly blue. hence, i conclude that his eye color is blue-grey. please keep it this way.
here is how the ninjapic looks with keith having purple eyes:Darvince 12:49, September 16, 2016 (UTC)
There's a post on tumblr that "proves" Keith's eyes are purple. I don't have it on hand, but be prepared for someone to bring it up. It uses screencaps, which again, for all reading, are subject to color change based on scene and production errors. Fwiw here's the image I used that clearly shows his eyes are blue: original and close-up - Ruriair (talk) 13:05, September 16, 2016 (UTC)
That altered pic is awesome! I've always thought Keith's eyes were more of a slate blue than anything else, nice to see some 'science' to back it up. Heh. Keith is the fandom's Elizabeth Taylor, from the way everyone insists on him having 'violet' eyes...Byrnstar (talk) 05:54, September 19, 2016 (UTC)
