Orange cheese

I just learned why the cheddar is orange in this country. I haven't seen any orange cows so, there must be a reason...Of course I understood it must be dyed, but WHY.... I needed to know, if I was to have a good nights sleep.... So I found the nearest orange cow and got a satisfactory answer...FINALLY. No i googled it. But it worked so hey.. Whey back when...( drumroll thank you!) ...the makers of cheese wanted it to appear that the cheese had a high fat content at all times, instead of the fluctuating fat content due to greener grass and happier cows, or less grass and skinnier cows...more fat, more color, yellow was good, but orange, now you're talking...so they used a dye from a tree called annatto....
