FYI real, fresh turmeric is a dull orange color with a tan papery skin. It still stains the hands and cutting board when chopped, but that's normal. As the root dries, it turns a dull yellow-orange.
I also know tomatoes are fruits, but in the comment section on the importance of eating fruits it would hardly be helpful to give as an example 'yes it's very important to eat plenty of fruit, such as tomato' - it's needlessly confusing when 'apple' would suffice.
