Hello i am near the end of the game and i have problems. How do i free the sisters ?? how to open their remaining hearts / each sister has 4 hearts i think ?? /

Great game i like it very much nice colours and really something new in game industry keep it up Great work

You can technically free all the Sisters if you want to and have the color (you won't), but to reach endgame, you only need to free one (fill all her hearts).

it does not answer my question on how i can fill their harts technicaly how to do this ?? how can i figure out which color i use on which sister

They are drawn on her tooltip (on the world map) and inside here camera obscura (top right-hand angle). There is a melodic sound effect when you select one of the favorite colours (at least, that's what I remember).

If you have some kind of colour blindness, this might become tricky, as there are apparently no text hints for sister's favourite colours. In this case use the map from this post: viewtopic.php?f=28&t=8932&p=96928&hilit ... map#p96928 (only Ole is wrong; she has Gold as one of the favourite colours, not Amber).

Of course, you may also make a screenshot of camera obscura and find out the colours by colour picker.

hehehe nice sense of humor love sarcastic comments i didnt know that i have to fill the remaining hearts with the same colours like first two / it should be two diffrent colours in my opinion /
one more question nameless sister /aka death/ died could she be saved ??

That was not humour. I have already seen some comments from colour-blind people. Though in most places game doesn't require you to see colours or perish, there are some moments when additional tooltips woulnd't harm. Given that several percent people have some kind of colour vision deficiency it comes as no surprise that amongst tens thousands players some have this problem.

Nameless Sister can be revived. Be prepared for a tough gameplay by the end of the game, though. You are going to need very much colour to set her free.
