colors for signage

[JayHawkInspector]

I have a question about the colors for ADA signs. The code says:

4.30.5* Finish and Contrast. The characters and background of signs shall be eggshell, matte, or other non-glare finish. Characters and symbols shall contrast with their background -- either light characters on a dark background or dark characters on a light background.

So does this mean the sign they paint on the parking lot surface for van accessible parking spaces could be yellow for the symbol and a blue background?

All I have ever seen is the blue back ground with the white symbol.

ADAAG does not specify the method or color in which accessible spaces are striped nor does it require placement of the access symbol on the surface of parking spaces. Local codes, not ADAAG, may contain requirements for the striping of spaces, including color, and any surface decals or designations.

Hey Jayhawk,

Mark's right. Local codes/laws sometime spell out what the colors have to be for parking space marking. In Missouri there are no color requirements for private parking but public street parking spaces set aside for accessibility are supposed to be striped in blue. But the symbol can be any color. (I'm sure Mark's also familiar with the California requriements that have the blue/white paint specifiied and specific text mandated in the parking aisles.)

Section 4.30.5 in teh ADAAG deals more with the signs mounted on walls and is not relevant to the painting on parking/drop off spaces. These criteria are set up for visually impaired individuals to be better able to read the sign. The markings on the parking spaces are intended to be seen by those with mobility impairments - differnt needs. Still it's a good idea to have contrast for all signage; it's just not required.

Rock Chalk!

What's not contrasting about blue and white?

It works... but so would red and white/ dark green and yellow/ pink and blue.

How doesn't bright blue contrast with pavement?

Zoning may tell you what colors are acceptable, but in parking lots, blue and white is the acceptable standard. You can't use glossy paint.

Color

Since 1990 the gound sign is not required. Above ground is specified in both codes. Signage requires a 70% contrast for buildings. Thus light colors on concrete would not pass and dark colors on asphalt.

That said, the color contrast requirement is general and the intent is for interior signage. One would not expect a visually impaired individual to have a drivers license. In Virginia parking signs under their control have specific guidelines.

We have a state amendment that specifies white on blue background (Washington).
