Sorry for not responding earlier, I have been away for 2 days. If you are afraid of too much colour with a bright blouse, you can go with a lighter texture, like lustre (or a gloss).
Anyway, if you are wearing bright colours, you need to put someting colourful on your face too, but one has to find a personal balance of course, and not to go OTT.
I have a book by T&S where they have these colour combination suggestions for clothes. This is what they say about black:
I never wear black unless I'm required by etiquette!
Not even pure black makeup, except mascara.
