As a child, colors have always been my "thing". Learning about them and using them to form child-like artworks, accessories, crafts and the like, filled my youth. With colors being relative to the expressions created by art, every hue and tone is of importance.
There are times when a certain color like "yellow" seems jolly and vibrant to some but, when mixed with other elements may seem otherwise. Children (unless they're gothic or are angry with the world) may at times use loud colors to extend their strong emotions to others. The loudness in turn, fool others to think that the child is joyful and carefree.
With the mixing and matching of crayola's/ markers/ pens from white to yellow to orange to blue, green and brown all the way up to black, you can be your very own Peyton Sawyer (of One Tree Hill) without appearing as obvious or as "emo" (a shortened term referring to one being "emotional").
Sharing how we feel as adults is always important but, we do not necessarily have to always banner them up on our sleeves. :) Always have a happy life. Be patient and true. :)
