Considering the principles of colour and how the human eye perceives colour is essential to developing a colour scheme or designing with colour. Keeping in mind the emotions relating to colour at the forefront of your research. The use of colour in a space can enhance important architectural elements and even deflect from areas that may be visually unpleasing. Colour has the ability to make a room feel larger, smaller, narrower, wider, higher, or lower. The key is to use colour to create the feeling the client needs and requests. Sometimes a client may wish for an ‘on trend’ colour palette. These trends change from year to year and the responsibility of a good designer is to guide and educate the client to complete a design that they will be satisfied with for more than just a season. This may involve using only certain tones of an ‘on trend’ colour to ensure a harmonious space.
