Mosaic and Striation Patterns

While judging colorbred, I like to show pictures to illustrate mosiac and striation patterns. The National Colorbred Association uses the Belgium COM standard.

Very good illustration of Mosaic Patterns on the cock and hen. Note the wing butts not the wings are colored and the proper mask on the cock. The hen's eye mark extends back from her eye and not forward toward the beak.

Comparison of striation on the undiluted black and brown (regardless of ground color, such as red/black - bronze) pictured on the left to the dilute such as agate in the black series and isabel in the brown series.

First of all let me say "It was nice working with you in Chicago."

These pics of standards are great!
Thank You Linda for the continuing
These pics lead to more questions.
Can you explain what judges look for in a show winning pastel canaries.
Should striations be visible?
How much ground color should be visible?

Looks like a book that these illustrations are in - is that book available anywhere?

Check with National Colorbred Association, Henry Vela for the manual. I will also ask him when I am in Dallas at the NCA National this week.

The pastel mutation is characterized by the reduction of melanin.

In Black pastel reduction of the whole design from black into a grey-anthracite color, Brown pastel slight reduction in normal melanin appears as a dense veil throughout the feathering which gives a brown bird with lipochrome color always visible and light striation, Agate pastel shows ash-grey fine and short striations with edges of wing and tail feathers being pearl-grey, Isabel pastel has a diluted melanin pigment and the beige color finely distributed with light striations on intensive and mosaics.
