So it works only with toned or multitone colors and only with _some_ greyscale pictures, not with bitmaps and also not with my greyscale dodo.
I can also only use one version my-blue – if I use my-blue-100, then my-blue-50 stays grey, and if I only use my-blue-50, it’s the same tone as 100.
Something’s very fishy.
