Colour of text

As the lead architect said the colour can change and its not set in concrete. I have decided that my text will be in black as this colour creates harmony with  also any colour. Furthermore this colour is bold and one of the easiest to read, after doing my questionnaire i found out way finding needs to be improved and i think the main factor is that its easy, simple and straight forward. Many guests will come to the building and want to find the room they want straight away this is why i have chosen such a simplistic technique.
