For me, = it is not about passing colour on to ConTeXt to typeset text, these are = colors that normally would be drawn with =E2=80=9Cwithcolor ca withtransparency = (method,factor)=E2=80=9D but that requires the passing of = many more parameters and a lot more work in coding.

Does transparent() maybe = produce a string that looks like =E2=80=9Cca withtransparency (method,factor)=E2=80=9D = so something only usable in draw/fill/etc statements? But in that case = how does that work without scantokens to parse the string?

Is there a way I can do = this without having twice the parameters (and I have to pass multiple = colours) in my macros everywhere?

Thanks,
