red is exciting, daring, jaring, warm and sometimes even evil. Yellow is cheerfull, happy, bright, eyecatching and usually a rather neutral color. Blue is cool (sometimes COLD and DARK!), soft, and the sometimes the color of life (water). A royal blue is usually masculine while a light blue can be a very feminine color. Green is a lively color but also the color of money. Pink is soft and feminine (sometimes overwhelmingly so). Purple is associated with royalty in its pure form and usually is another feminine color in the pastel version. Orange is rather bright and intelligent looking (if a color can be intelligent). Greys are rather dark and neutral and tans and browns are earthy colors. Be aware of these connotations when you pic colors and hues of these colors. (and we all know that most self-respecting villains prefer darker versions of these colors).
