Most  of the Japanese cartoon art is usually three and two dimensional and  you will find the use of bright colors is always in constant use and  help create a montage of various color use. The cartoons are able to  look life like because of the use of the colors which help in creating a  more realistic look at human emotion. This way we are able to tell if  the cartoon is angry or annoyed, by the red cheeks and also if they are  sad or sick they usually turn different colors or more pale than usual.
However  the colors are not the only thing that the Japanese artist uses to  denote emotion. The use of the large western like eyes is also used  quite frequently and many times I have always wondered why the use of  western characters, have become a big theme in most of the Japanese  animated movies and series.
I guess its because the whole world looks to the west as the main super power countries and it is easier to use them as characters in the animated movies.
