Dim the unlocking background and/or option to change the pattern dot colour

[WildS0ft]

It just occurred to me that if you are using a very light or even white wallpaper where the dots are in the pattern unlock, you'll be having a hard time seeing them.

A workaround would be to dim the background like in Android's unlocking view or to be able to change the colour of the dots.

@WildS0ft You can already use the invert color option from the lockscreen ui settings.

Ah, I have missed that option for some reason :neutral_face: Still believe "my solution" would be neater though :bowtie:

However this will help a lot until the other bug has been dealt with :smile:

What is in my opinion the most suitable way is contrast detection of the background image, with Palette API and android.support.v4.graphics.ColorUtils.calculateContrast().
