In most cases, you are correct. For example; my clan has a burgundy background with four medium width green bars, and two narrow white pinstripes between each set of green, easily recognized as Crawford. A LOT of clans have red and green, but I can change the white to black pinstripes, make the green dark brown, on a field of tan, and it would still be recognized as Crawford (camo) regardless of color. Then there are Chisms and Camerons that have 4 green bars and 1 pinstripe; white for Chism and yellow for Cameron. After the b/w narrowing it down, the colors would be used as secondary.
I like it. Thank you Richard.
