If surveys are to be believed then in case you work or interact with the world of Digital Marketing, images are considered to be crucial for achieving social media goals and more than 70% users prefer image based posts over text.
It has been found that complex images in social media tend to capture greater attention. It has been found that posts with images which take up more screen space tend to benefit more from complexities of color. This also suggests that timing and visual prominence of posts play a greater role in maximizing engagement.
Though not much has been documented but still research is going on in this arena. For the betterment of content creators and marketers, investment in careful curation of social media images with high color complexity can lead to better user engagement so therefore be mindful of the timing and the context also.

Color complexity is quite similar to colorfulness but it’s not quite the same and is measured as color variation across pixels in an image which our brains process it subliminally. The more brain has to decipher color variations across neighboring pixels, the harder it has to work.
Here the ongoing research is filling the gap and it is suggested that nuanced approach to image design and incorporation of high color complexity where needed can definitely enhance user engagement.
