Color is one of the tools of the designer that is responsible for the success or failure of the design. It must be added to achieve the desired effect, and integral part of the architectural material. Color in architecture serves to distinguish items, to attract and strengthen the interest of the observer and reduce eye contact. No matter how innovative the design techniques maybe, without color, the final appearance of any design becomes hard to perceive. Temperature and mood are all influenced by the choice of color design. Colors such as red, yellow and orange create a feeling of warmth, informality, cheer and exuberance. Colors such as blue and green can create a feeling of quite, formality and coolness.
The visual dimensions of a building can be changed by color design. A room can be made to appear higher or longer and lower or shorter. Bold colors such as red create the illusion of advancement while pale colors tend to recede. A tint of a hue will make a room look larger in area and by varying the value properties of a color, a room can be changed in terms of mood. A tint can be produced by the addition of white to a base color.
To make a room smaller and fuller, a dark shade can achieve such goal. A shade can be produced by adding black to a normal color. It is also important for architectural designers to remember that with continued exposures to light colors, visual sensitivity decreases so the effective designer plans the relationship of light and dark areas accordingly.
It is possible to have a perception of dullness from an area of a design that lacks variety and that is tiresome to the eye of the observers. To much rhythm, too much repetition, and too much unity ruins the sense of variety or contrast. Likewise, too little of the elements of design will also result in lack of variety. Light, shadow and color are the important aspects of a design that are utilized extensively to achieve variety.
The designer must have a thorough knowledge about the basic elements of the design to create a functional plan but must also be on guard and do things that relate to the changing styles and taste patterns. There are times when people prefer one style in a given time and in another times, the complete opposite is chosen as preference. Public taste constantly change but the designer must not be caught in some "fad trap" and must be alert to recognize the difference between fad and trends. He must be able to see the link between the past, present and future. And effective creative designer must be able to remember the past experiences and apply old ideas to new situations in order to have a combination of unlimited variety.
