Yes, most of the markings are blue. I've attached a converted version, though I'm not sure how well a two-page document works as a PNG.
You really should find yourself a way to display things as monochrome. Blue should turn out as a dark grey.
To be fair, even for people who are not colour blind (my employer insists on testing me at every medical and apparently I’m normal, I often joke with the nurse that I’m far from normal
), some of these multicoloured schematics do my head in.
The different bright colours can be distracting, and if you try to print the diagram out, you either need a colour printer (with all the cartridges operational). Or printer driver for your monochrome printer that is actually good at producing sensible gray shades (not all are).
You just can’t beat a well laid out schematic diagram that is clear, no overlapping symbols or text, uncluttered, easy to understand, puts blocks that are relevant next to one another and is easy on the eye. There should be no need for colour. My feeling is, if you need colour to ‘make it work’, then your schematic diagram is poor.
The only time that I deliberately set out to use colour, is when I want to show existing circuitry and modifications on the same diagram (for example when documenting wires added to an existing PCB to overcome a mistake in the track layout or when changing the design for any other reason).
Sometimes I use colour if there is something that is really important that needs highlighting and bold text alone is not enough (high voltages for example).
Not all, but often if you look at the hand drawn schematic diagrams from the past, the person that drafted it took pride in making the diagram clear, logical and easy to read.
Far too often nowadays, a schematic is nothing more than a bunch of rectangles with text listed around the sides. Often much time can be wasted hunting for the ‘other end’ of a signal as you cast your eye around looking for a match. It’s fair enough if a signal line is part of a bus (address bus, data bus etc.) to put them in a group.
But for independent signal lines, or control lines, I much prefer an actual line to follow. Or alternatively if there are only two nodes, for the text to indicate the source or destination of the signal (at each end).
It’s a similar story when choosing whether to depict a chip as a rectangular box, or a symbol that enables the reader to more easily recognise the function. So I prefer the American logic symbols for example.
