Colour Theory Colour theory Colour theory in the visual arts is a practical guidance to mixing of colours and the visual crush or impacts of combination of specific colours. There are categories of colours which are primary colours, secondary colours and tertiary colours. Therefore. colour is a matter of light. There can be no colour without light. First, all the visible colour spectrum contains all white light. This implies that when the colours are together, with the same amount of intensities, they make the white colour. For instance, the light from the sun is a white light. When the sunlight is decomposed, it makes all the colours in the rainbow (Albers 2006).Many people are aware of colours from painting or as paints. In this regard, when we mix yellow and blue, we get a shade of green. On the other hand, when we mix 100% red and green light, it will create yellow. When we take into consideration the colours that the monitor produces we realise that they are generated by the light beams, based on the RGB model. It is referred to as ‘addictive colour model’. When it comes to printing inks or paint, it is based on the CMYK model which is referred to as the ‘subtractive colour model’ (Albers 2006).RGB colour model is a colour that is based on light. These three colours are the three primary colours with green replacing the colour yellow. When the three colours are combined, then it becomes possible to produce any other colour. This colour model is only used with source of light and does not apply to printing (Albers 2006).CMYK colour model is the colour method that is based upon pigments. The initials stand for Cyan, Magenta, Yellow and Black. K stands for black. When the four colours are used, it becomes possible to achieve other colours. CMYK model cannot reproduce the same amount of colour as the RGB colour model. This is the reason why when printed yellow-green at times appears slightly muddy. This is the method employed by printers the world over. It is also an intelligent way or mixing paints (Albers 2006).Colour space is a helpful conceptual tool for comprehending the capabilities of colour of a digital file or device. Thus, when one is trying to make a reproduction of colour on another device, the colour spaces reveal whether one will manage to retain the highlight or shadow detail, the saturation of colour as well as, by how much wither of the two will be compromised.The process of keeping colour consistency in digital photography runs from the minute one takes a photo, uploads it to the computer, converting the same to jpegs and printing it using a variety of output technology. The process of editing an image involves the existing profile of the image. This is what is referred to as a working colour space. Three primary working spaces for editing images exist. They are sRGB, AdopeRGB and Adope Photoshop: ProfotoRGB (Albers 2006).BibliographyAlbers, J, 2006 ‘ Interaction of Colour. Revised and Expanded Edition’. New Haven, Yale University Press.
