Very impressive article Jake! You are very talented.
nice article! i love seeing the breakdowns.
Color cycling from the 90s, a technology used in 8-bit video games to achieve interesting visual effects by shifting the color palette, is back! Back then game developers used the technology to animate water, fire or other environmental effects. There was one artist that took color cycling to a whole new level. Mark J. Ferrari invented his own techniques of using the technology for scenes. He achieved all his effects without any layers or alpha channels — just one single flat image with one 256 color palette.
The technique then died, but Joe from Effect Games thinks that it’s time to bring it back, using open web technologies like the HTML5 Canvas element. The artist shared a demo which is an implementation of a full 8-bit color cycling engine, rendered into an HTML5 Canvas in real-time. He used 35 of Mark’s original 640×480 pixel masterpieces and I added some ambient environmental soundtracks to match. You can find the demo here.
Q & A with Mark J. Ferrari
Those of you familiar with color cycling may notice something a little “different” about the palette animation in this engine. Many years ago I had an idea to improve color cycling by “fading” colors into each other as they shifted, to produce many “in between” frames, while preserving the overall “speed” of the cycling effect. This creates a much smoother appearance, and gives the illusion of more colors in the scene. I call this technique BlendShift Cycling. Someone may have invented this before me, but I’ve certainly never seen it used.
You can really see the effect this has if you slow down the cycling speed (Click “Show Options” and click on either ¼ or ½), then turn BlendShift off and on by clicking on the “Standard” and “Blend” cycling modes. See the difference? The colors “shift” positions in whole steps when using Standard mode, but fade smoothly into each other when using BlendShift. If only I’d invented this trick 20 years ago when it really mattered!
