Few points here: > Text being unreadable due to no spaces at all." Text without spaces is readable. Text with spaces is more readable. Readability is a continuum. Literature is certainly readable without bold, italics, underlining, and indentation. Colored text, for people with normal vision, remains clear. Clarity is not lost, another channel for transmitting information to the user is added. We don't use color highlighting in books, but perhaps we should. I haven't tried it, so I cannot say it would not be better. I have heard it suggested that coloring lines of dialog would make literature easier to read. I think it is very plausible that Shakespeare in particular could be made more accessible with the use of color. With the rise of ebooks, this sort of experimentation is now feasible and I think that it is likely that we will see people experimenting with this sort of thing as the new capabilities that ebook devices provide give us an opportunity to revisit some traditions that were originally set in place by material constraint. And lastly, code is not read as literature typically is. Most literature is written with linearity in mind. Most code is written under the assumption that the reader will jump up and down it repetitively, frequently jumping to random locations in the file. Coloring code therefore becomes useful in much the same way that coloring road atlases are useful. You don't need to trace a road back to the nearest label to find out that it is an interstate; you can tell right away because it is blue. That big area inside of that squiggly line? It's a state park, you can tell because it is slightly green, so you don't need to look around on either side for the dotted line surrounding it. That green area in the middle? That's a comment, you can tell without scanning your eyes to either side looking for comment characters...
