All permanent directional and identification signs are required by ADA to have a sharp contrast between the colors of the letters and background, and a non-glare finish.

Make all signs the same color so people will come to recognize them and look for them when they need information.

For temporary signage choose a mat board color first since you will use this materials most often.  Take a piece of the mat board to a paint store and have a gallon of paint (flat finish) mixed to match the mat board so that painted masonite boards (overhead signs) will look the same.  See Fabrication for more details.

Be careful that any protective coverings used on signs do not cause a problem with glare.  This is especially difficult for people with visual impairments, and is annoying to all.  If you must cover signs or maps use non-glare glass, or matte finish acrylic or film.

Attach to this page a sample piece of mat board in the color(s) used for your library signage.  Write the color number of the mat board and also the brand and formula for the matching paint.
