Reduce intensity of too dominant colors

[FaKo97]

For most of the images I use blurhash on, the result looks nice and as expected. But there are images, which look kinda weird, because of the color scheme of the decoding produces.

Here are some examples of what I mean:

These very intense color "drops" appear and disappear, depending on the number of tiles, so it would be possible to get the best outcome, setting the components manually. But I want to get blurhashs for usergenerated images, so I need an overall rule to set the amount of components.

Is there anything I can do in this situation?

I'm working with the dart implementation on Flutter.

@FaKo97 have you found any solution for this?

You should increase the number of components. I see you're using 2x2.

If you need a short blurhash (although this would only make practical sense if you have tens or hundreds of millions of images), I suggest preprocessing the images. Downsize to 32x32 and then try changing the gamma or moving the black point higher up. (Similar to the Levels function in Photoshop)
