> Yes they have? It's a fairly common method of teaching children sentence structure. I literally mentioned it for learners. I meant for "improving reading speed". Syntax highlighting is like a crutch that helps you walk but is slower than being able to walk normally. > Why do you feel the need to intentionally hobble yourself? The human eyes can take in a spectacular amount of visual information at a glance, using colour, texture, shape and so on to instantly classify and identify things. [...] Decades of visual design research have proven that colours and shapes [...] Because the colors and shapes you're talking about are for differentiating things. Colors and symbols improve understanding when used sparingly, if your UI is just a page full of colorful shapes and symbols it becomes a nightmare to navigate. Likewise, differentiating every third word in a sentence is counterproductive. It's text. We spend our entire lives reading text. Our eyes are already trained to skim text as a unit. I seriously doubt there's any research suggesting that making every word colorful and breaking up their flow improves reading speed compared to letting the text be a cohesive string you can parse quickly.
