  1. Understanding Caramels & the Dilute Modifier effect Deb Armishaw

  2. Black versus Red • pigment in cats comes in two basic forms. • Eumelanin is the dark pigment • it produces black, brown (i.e. chocolate/cinnamon) colour • Phaeomelanin is the bright pigment • it produces red colour

  3. Dense Colours • Black = round shaped Eumelanin granules • Chocolate = oval shaped Eumelanin granules • Cinnamon = spindle shaped Eumelanin granules • Red = round shaped Phaeomelanin granules • dense coloured pigment granules tightly pack hair shaft

  4. Dilute Colours • Blue = clumped round shaped Eumelanin granules • Lilac (Lavender) = clumped oval shaped Eumelanin granules • Fawn = clumped spindle shaped Eumelanin granules • Cream = clumped Phaeomelanin granules • dilute colour pigment grains clump together in hair shaft

  5. Dilute Modified Colours • Blue Caramel = break away single + clumped round shaped Eumelanin granules • Lilac (Lavender) Caramel = break away single + clumped oval shaped Eumelanin granules • Fawn Caramel = break away single + clumped spindle shaped Eumelanin granules • Apricot (Cream Caramel) = break away single + clumped Phaeomelanin granules

  6. 3 Lavender Caramel Oriental Kittens with a Lavender & Blue

  7. Effect • colour granules are clumped • single grains break off • muddies the light in the hair shaft • causes the blue, lilac, fawn and cream to modify • appears to have a browning effect • Coat can have metallic sheen

  8. Caramel is the modification of a colour. • Like tabby or silver it does not and can not stand alone. • It has to have a colour to exist. • It is impossible for a caramel to appear in a litter of two blue, two lilac, two fawn or two cream parents. • The Dm gene has no apparent effect on dense coat colours (Turner, 1992; Vella et al, 1999).

  9. Dense Dilute Modifier Dilute Blue Caramel Blue Black Lavender Caramel Lilac/Lavender Chocolate Fawn Caramel Fawn Cinnamon Red Apricot Cream

  10. There are four base colours • Blue

  11. There are four base colours • Lilac or Lavender

  12. There are four base colours • Fawn
