Agreeableness
The agreeableness trait is characterized by social harmony and cooperation. Users high in this trait like to have profile pictures with faces in them. For colors, the correlations are almost all opposite to those for openness, even though the two traits are uncorrelated in both surveys and text predictions. Agreeable people use colorful pictures (but to a lesser extent than extraverts) which are low in sharpness, blurry and bright. They tend to respect the rule of thirds, but the edge distribution is strongly negatively correlated, hinting their pictures are cluttered as opposed to simple. Color emotions are highest across all traits, a fact also indicated by the presence of static and dynamic lines. This leads to the conclusion that, although bright, colorful and color emotive, pictures of agreeable users are not the most aesthetically pleasing. Facial presentation features show very low magnitude correlations.
Facial emotion patterns are similar to psychology theory: very strong correlation with smiling, joy and overall positive emotion and low in all negative emotion expressions. This corresponds to the color correlations. Intriguingly, this is different to conscientious people who are highest in facial positive emotions, but do not express this through the overall color tone of the image as agreeable people do.
