These are leftovers from the typewriter age. Use bold or italics instead. Do not use italics on your web site or they will look like the italics in the previous sentence. You have total control over what is said and how, including the visuals. You control the selectivity of where your brochure is placed and who gets it.
Brochures are flexible.
You can design the brochure in color, print it in black and white, until you can afford the expense of color printing. You can do it yourself. Although I would recommend professionals as soon as you can. You should give your brochure to all qualified customers. However, using it for mass audiences may be cost prohibitive.
