Are the colours of the signs synonymous with the area or activity?
The colours are entirely a matter of choice but we will provide advice on colour combinations if requested. Having said that, where the toilets are concerned, our recommendation, based on the best current knowledge, is that Red or Yellow are the most effective colours to employ here for the signage, the doors and the toilet seat. The result being that the residents are very able to learn that this highly visible colour represents the location of the toilet. Naturally, one will then avoid using this colour for anywhere except the toilet.
