In terms of character, greenways should have many colours. The above discussion is mainly about greenway function. It is also necessary to consider greenway character. In a 1996 essay on Harlequin Space, I argued that cities need 'parks' which are red, blue, yellow, brown, purple, white and green (Turner, 1996). Redspace is exciting, Bluespace is serene and cool, Yellowspace stimulates one's curiosity, Orangespace is gay, Brownspace is wholesome, Greyspace is solemn, Whitespace is spiritual, Greenspace is calm and relaxing. The colours symbolize characters. As with paint, the primary colours are red, yellow and blue, but they can be mixed. Many combinations are possible [Fig 4.24]. Greenways too can be made in different hues [Fig 4.25]. 4.25 Colours can be used to symbolise the character of greenways.
