I have a white car.

I went to a car manufacturing factory and saw how they make cars. The body is silver at first they dip the entire body into white paint.

So is my car white, or is my car covered in paint that is white?

In spring the leaves are green. but in autumn they change to yellow or red, then eventually to brown. What is the true colour of leaves.

Two trees have green leaves. Taking a sample and putting the leaves side by side they are not identical in colour. One is lighter than the other. Why do we still call them green?

A book is sitting on my shelf. It has been sitting there for years. One day, I take the book off the shelf to read and notice that the edge of the pages have yellowed ever so slightly compared to the inside of the book. Yet when the book was on the shelf I still thought was white. Is the book pages still white in that sense?
