ISO #10

[camio]

Finally, colours are to be avoided in ISO documents for accessibility reasons.
The underlining and strikethrough should be enough to differentiate between
additions and deletions. Is there a specific reason why colours should be
used? If so, please add an explanation/definition of the colours in new
Clause 4 about conventions and add the following paragraph before Clause 1:
IMPORTANT — The electronic file of this document contains colours which are
considered to be useful for the correct understanding of the document (see
explanation in 4.X). Users should therefore consider printing this document
using a colour printer.

So do we want to keep the colors? I couldn't think of a compelling reason, after going through the document.. we don't have any charts/graphs that would require colors.
