Feature request: color specific meta information

[genox]

Thanks for publishing this project.

One small thing I couldn't find in any OSS image proxy solutions (and I was searching for days) is color specific meta information. This would be quite handy from a designer perspective and it is one of those things that makes me look jealously to something like imgix or imgxproxy pro. ;)

This is keeping me basically from dropping SaaS CMS as I find myself using this frequently.

• an array with dominant colours, with [0] being the most dominant
• an average light colour and an average dark colour
• a light/dark flag, based on the average colour
• ...

Also adding the thumb hash to that would basically give us feature parity with SaaS solutions on the meta subject I think.

There are many possibilities that would make creating more visually dynamic UIs in apps or the like much easier with a backend offering such information.

Thank you for considering.
