Signs.

Looking at the two new buildings, they need some signage.
So into MS works- or something like that and after a few minutes hey presto- the signs for the buildings is before me.
Unfortunately I am too much of a ludite to know how to colour the background of these so they will have to remain white.
I may try a gentle rub with a pastel stick to see wether I can infuse some colour or someone is bound to tell me how to do it- or even better- do it for me.
Any Offers?
