Hi Cvenkel,
I don't understand very well the photos you post.  But seeing the verrucas and the title of this topic, I think that Verrucaria marmorea is an option.
Regards,

Re : Violet lichen on stone- spilled juice appperance
See attached photo, to get better filling how it loooks, 'purple area' about 5 cm across.

Much different than this: Verrucaria marmorea

Ok one could speculate there is something brighter inbetween there too.
But no such thing visible from far and no copletely clear areas (clear white stone) there.

Re : Violet lichen on stone- spilled juice appperance
Thanks for the new photo that was clarifying. Indeed, this one looks different. Notice, however, that the fruting bodies are similar. Therefore, it could belong to Verrucaria or a closer genus.
Salutations,
