The crossing tables are built in squares for each colour. The rows and columns responsible for a pattern (Bicolor, tabby, etc.) are underlaid with grey colour.

Example

In this example the square, which is concerned, is circled with blue colour.

			Bicolor		Bicolor

	black	black	black Bicolor black	black black Bicolor black black Bicolor black black Van black Bicolor 1) 1)

Example 1

You cross a chocolate Bicolor male with a black female.

For the colour of the male mark all the cells down the column "chocolate Bicolor".
For the colour of the female mark all the cells along the row "Black".
Then look at the whole square (circled with red colour), in which these two colours meet each other, here you will find the result of this crossing.
