Prof. Jain?? has classified the colours as pigmentary, natural and spectral. He has suggested that the philosopher's colours are the natural ones. Does it mean that rainbow colours are not natural ? He has differentiated between pigmentary and spectral colours. However, this does not make any difference in their number and spectrum ranges. Whatever be the colour, it will be perceived by its spectral characteristics. It is on this basis that pigmantary colours are said to be of mixed spectrum and saturated one. Moreover, his comments in support of the number of canonical colours requires reconsideration. Jain73 has suggested a way out. He points out - there are two types of colours – atomic and molecular. The Jaina colours represent the atomic colours which are basic three - red, yellow and blue. The rest two being called formal rather than basic ones. This logic may be applicable to all the qualitative discussions and per chance this may solve some of the problems and increase scientificity in Jaina concepts.
The spectrum range of the colours (blue-red) of the Jainas and other Indian philosophers represents that of only five colours of the scientists. The philosophers have accepted only three of them (blue, yellow, red). This should not be taken as a large defect looking to the pre-instrumental age observations. Their range does not include ultra-violet, violet and indigo colours. On this basis and by the composition of white colour, scientist's observations seem to be finer and more accurately additive to the canonical ones. The canonical infinite variety of each colour, however, is substantiated by the spectroscopists as each of the seven colours represents a range of spectrum rather than a specific one. Attribute of Shape
While defining mattergy, the word 'rūpa' or 'form' was coined. The form is denoted by shape. It is also a property perceivable by the eye. This is property of extension in space in two or three dimensions. Some Buddhas presume?4 form and colour as inseparable as one cannot exist without the
