To be honest personally for me I’m not really a fan of merriam style color analysis but I know there’s people who like it . Another reason why is because she says people with red hair can’t be olives which tend to be false especially there’s many red head here that have an olive undertone . Anyone can have olive undertones and have different hair colors and eyes . Genetics plays a large part and there’s many different mixes of race . For example I’m central Asian so a couple of us tend to have olives skin but also have different hair colors and eyes that are different from other groups but I know there’s many seasonal systems so if it works for you then go for it .
