Abstract
Color is a main channel to express emotions of an image. Selecting a good color scheme with color harmony and proper emotional expression is very important in many fields, such as design. There are many color palette tools to help users search, create, edit, save, and share color themes, but few tools are from the perspective of emotional expression and explicitly address the emotional effects of colors. In this paper, a color hunt system with affective words called ColorEmo is developed. Multiple types of input, including affective words, affective categories in image-scale space, and main colors, are allowed for users with accurate emotional description. Based on the dataset with 428,924 color themes, the system provides rich candidates. The system is designed for user research experiments. The user-friendly interactions are offered for easy color modifications. The affective matching and color harmony are evaluated in real time while changing colors. This system can be used in many scenarios of designs and applications.
Highlights
Even designers, lack color scheme knowledge. They are hard to distinguish the good and bad candidate color themes, which are always mixed in most systems. After they modify the candidate color theme, they do not know whether it is in line with the emotion and color harmony rules
The assessment algorithm to evaluate how well the color theme matches the emotion and color harmony rules is the key function of the system
A complete system called “ColorEmo” is proposed to hunt colors based on affective words
Summary
With the proliferation of Cyberphysical Systems (CPSs) [1,2,3,4], finding a set of colors for matching different scenarios of practical applications can be tricky. Much of the feelings about an image are expressed by colors even if the context is important. Based on the study of human color perception, there are many color harmony rules to describe the matching relationship among colors in a color theme, and some color schemes are provided. Even designers, it is difficult to find the proper color theme when using color palettes. There are many color palette tools to help users find color themes from the perspective of different user demands. Few color palette tools are from the perspective of emotional expression and explicitly address the emotional effects of colors
