Red is a primary color and cannot be produced by mixing other colors. Red, blue and yellow are the three primary colors. Only secondary and tertiary colors can be fabricated by mixing the appropriate colors together.
A fact is a piece of information that can be strictly defined and proved true. An opinion is a statement that expresses a belief, value, or feeling. An opinion cannot be proved true or false. For example, a person's age is a fact, but if someone is asked how old they feel, it is impossible to prove the person's answer to be true or false.
If someone can disprove a fact, then it never was a fact to begin with. Opinions are a personal view, either based on fact or fiction. For example, grass is green is an opinion, given grass can be blue or brown, etc., etc., so it is not a fact that grass. is green.It can be, but it is not always the case, or as stated earlier, religion is opinion and not fact.f he isn't telling the truth it's neither his opinion or a fact. If I'm arguing with someone else in a room about what object is on the other side, it doesn't change the facts of what's on the other side. My opinions are either true or not true. I can open the door to find out.
