There is huge difference between these two ideas: hsl = hsl + [.5, 0, 0] and hsl = [.5, 0, 0] The latter would be 180º hue, and 0 saturation and lightness. The first one would be the existing color, plus 180º but no change in saturation or lightness. What is the initial color you are using?

Tell me how this solution is correct: To get your hue shift, you set the hsl value to hsl = hsl + [hue,0,0]. The part in braces is hue value = x, saturation = 0 and brightness = 0. Well, by how I look at it, a saturation value of 0 in hsl terminology is white. Thus I'd see no color variation, which is what I experienced. When I changed the variable to hsl = hsl + [hue,1,0] everything started working. How is that possible? OK, I don’t understand why your tutorial worked, but I got it to work for me.

By that I mean the colors never change. I know I did the tut correctly, in fact, I did it twice to be certain. The slider numbers change when I scrub the timeline, but... nada. Any thoughts?

Tried in both Safari and Firefox. I checked several other tutorials on your site to be sure and they all played perfectly. Thanks for your great work! Oddly, I couldn’t get the video to play, either.
