Saying not to use color because color blind people cannot see them well or at all is somewhat like saying to not use pictures and diagrams at all because blind people cannot see them, or not to have advanced math or physics texts because they are beyond the comprehension of many.

Rather than reducing all communication to the lowest common denominator of human capability, we should be able to use all of the tools available when they are useful.  Use of color for mere decoration should be avoided, and back-ups are welcome when available. 

Colored lines are useful in identifying wires, but backing them up with labels is also helpful.  And we should also beware of situations where color is harmful.  Use of only an approximate color, or worse a color that seems approximately right on a poorly adjusted monitor, combined with wires that also have a weird initial hue that has further drifted with time can actually be worse than no color.

If you really do want to help color blind people, then avoid relying on color, or using unnecessary color effects like gradients that can distract.

Modification accepted :)

Colour - when used judiciously - can enhance the content/intent/message.

Too often it is used poorly; either the colours are irrelevant or detract from the content, or in extreme cases they obscure the content.

It is usually possible to avoid using colour to convey information. Graphic designers may not like the result, but then they are responsible for far too many dismal web pages :)


--- Quote ---Visualization is all about controlling the information conveyed.  If you limit to the simplest set of tools, most will perceive the images as dull and information-sparse.  The trick is to ensure the most important information is clearest to all, and use the tools that do not work for all viewers for the less important but still mostly useful information.  (Also, even if one knows all the rules and tricks, applying them and getting nice results is still a different thing.  Just look at mine: I know more about visualization than most, and yet mine are just adequate, nothing special.)

Agreed - and nobody has advocated that.

Agreed.

Now, exactly what is the colour of "the dress that broke the internet"?



For the answers, start at https://en.wikipedia.org/wiki/The_dress "The study, which involved 1,400 respondents, found that 57 per cent saw the dress as blue and black, 30 per cent saw it as white and gold, 11 per cent saw it as blue and brown, and two per cent reported it as 'other'"

Tation:
The wiring schematics of a motorbike I owned were drawn in colours so that each connection matched the colors of the real wire in the bike, and there were no repeated color combinations. All wires in the schematic were in two colours, say a green "core" with yellow "sides".

Always wondered about what tool did they use to draw such schematics.

RAPo:
if you want some programming control over vertices/edges diagrams, take a look at yEd.
