Colour; therapy and the mind

Been having a few issues of how to put across what I want to say in my contextual analysis/ review. I know what I want to say but don't know how to word it.....I know I want to say about how people see colour and the meanings behind colour. how colour can effect people and how Catherine Yass uses light boxes and how to me by using light and colour together it can draw us in. from my own experience I see bright colour in my work and around me. Also mentioning about colour therapy and sensory rooms for the disabled can help. think i need to research more into how people see colour and not be so physiological about mental health and focus more how colour can help the mind.
