Example text

The colours that are indistinguishable to dichromats are located along lines that converge at a single point. This point of convergence is known as the confusion point, and is characteristic for each deficiency type (identifying the chromatic co-ordinates of the missing response mechanism, although in practice there would be an influence from absorption of the pre-receptor media). 3 Two different colours C1 and C2d will be similar for a tritanopic subject. T and D responses are equal. 4 Protanopic confusion lines.

The ideal atlas should be highly stable and should have good fastness properties, particularly to light. It should be simple and easy to understand. The samples are to be reproducible and replacement pieces should be available. It should be cheap, portable and globally used. However, no atlas is expected to represent visually millions of colours that can be detected by our eyes. There is no ideal colour order system and hence no ideal atlas. 1 The necessity of a colour order system It is a difficult task to deal with the millions of colours which our eyes can distinguish.

In this system, effort has been made to arrange colours in some definite order, however the spacing of the samples is somewhat arbitrary and not equally spaced. The system describes a very small portion of the colours visualised by us. Intermediate colours can be interpolated, but such interpolation cannot be communicated to others because the samples are not spaced equally as per the visual colour perception. Colour appearance systems These systems are based on the perception of colours by an observer with normal colour vision and the scales are chosen to represent attributes of perceived colours.
