When it comes to colors and patterns, sometimes I think you have to almost make up your own mind as to what is true and what is not, especially when there is no test avaliable.
When I first started in minis, and was using a lot of overos and/or overo background, I was told just about everything under the sun. I researched and found 4 different people with a lot of background in overos.
All 4 of them were telling me different things, some small things, but still different. EACH one of them were very sure they were correct and the others were wrong. As a newer person at the time, how in the world do I decide who is wrong and who has the correct, actual information? Each one of these folks would have faught to their death the info they were giving was the RIGHT info.
I have seen the same with color, time and time again.
So I read all I can get my hands on, pay attention to info given using test results that are avaliable, and the rest I go by what I have seen to be true, but keep all the other information at hand for reference.
After all, if there is no test,,,,,,,,,who is to say, who is right???
I say we learn what we can, from any information made avaliabe to us. I am not sure of the errors here, but still found the article interesting and maybe I picked up a thing or two.
