UNDERSTANDING THE PF WIKI EYE COLOUR CHART
Note: If you found this page through any means other than via the Pure Felinity site, you should be aware of the fact that this page was written about cyber cat breeding, not real cats, and that it is tailored to the breeding rules of this site. The genetics of this site are a simplified version of reality, so there may be some principles that do not hold true in real life.
Each eye colour is made up of three factors: the base colour (yellow, orange or brown), the colour intensity (level 1, level 2 or level 3) and the blue tint (0, 1, 2 or 3). The Eye Colour Chart on the PF Wiki is an attempt to graphically represent this fairly complicated concept. Used properly, it makes calculating the potential eye colour outcomes of any mating much easier, but it does seem to cause some confusion.
The first thing to understand is how the three factors affecting the eye colour are represented on the chart:
The first three rows of colours all have yellow base colour:
The next three rows of colours all have orange base colour:
The last three rows of colours all have brown base colour:
On the eye colour chart, the number of stars in the left-hand column (titled 'intensity') indicates the intensity level of the base colour, with * meaning level 1, ** meaning level 2 and *** meaning level 3. In each case, the first row of the base colour is level 1 (i.e. colours 1, 10, 19 and 28 on the first image below, 4, 13, 22 and 31 on the second image, and 7, 16, 25 and 34 on the third image), the second level 2 (i.e. colours 2, 11, 20, 29, 5, 14, 23, 32, 8, 17, 26 and 35) and the third level 3 (i.e. colours 3, 12, 21, 30, 6, 15, 24, 33, 9, 18, 27 and 36).
On the eye colour chart, the number of stars in the row titled 'stroma' indicate the level of blue tint, with 0 (clear) meaning no tint, * meaning level 1, ** meaning level 2 and *** meaning level 3:
The second column
(titled '0 (clear)') contains the colours with no blue tint
The third column
(titled '*') contains the colours with level 1 blue tint
The fourth column
(titled '**') contains the colours with level 2 blue tint
The final column
(titled '***') contains the colours with level 3 blue tint
Having understood how the chart represents the different factors making up the eye colour, you can then use the numbers to read the colours off the chart.
Using the Numbers
Each box on the chart represents a different colour, and each colour has a number assigned to it. To find out the name given to any individual colour, read the number from the relevant box, and then read the name given next to that number in the list below the chart.
The number-colour combinations are listed in groups of pale, medium and deep colours. Understanding the groupings is a lot easier once you understand how the base colour, colour intensity and blue tint work together to create the various colours.
To use the yellow base colour section as an example:
1, 2, 3 - Yellow without any blue tint obviously gives pale, medium and deep yellow, depending on the intensity
10, 20, 30 - Equal amounts of yellow and blue gives green (pale when both are level 1, medium when both are level 2, and deep when both are level 3)
11, 12, 21 - Higher levels of yellow than blue give yellowy-greens
19, 28, 29 - Higher levels of blue than yellow give bluey-greens (aqua)
Working Backwards From Colour to Components
The same process is possible in reverse, to establish the components making up any individual colour. For example, if you want to know what factors make up deep grey-green:
|Find grey-green in the colour list, and note the number||- number 32|
|Find number 32 on the chart||- about 1/2 way down the right-hand column|
|Read across to the left to find out the base colour and intensity||- orange, level 2|
|Read up to find out the blue tint level||- level 3|
Having worked out the components of the colour, that knowledge can now be used to work out what eye colour the kittens may have.
