Images for neutral emotions are too colourful

[davidfoerster]

Emotionally neutral phrases are mapped to grey colours and associated images are supposed to be grey and of low colour saturation. At the moment they turn out too colourful.

One remedy would be to raise the influence of the (grey) colours on the image search but this reduces the result set size (sometimes drastically) which is undesirable since we need to rely on key words alone instead of emotions.

An alternative solution is to desaturate these images at some point between retrieval and display.
