[BUG] Theme White Checks not visible

[ghost]

Hello,

If I use the white theme I can not see if something is checked or not as the checks have a white color and the background is also white.

In the black theme everything looks nice.

@jpeg729 maybe it is an idea to calculate the brightness for the activated highlight color and compare this to the brightness of the background color and invert the color if the difference is to small.

Not very good researched, maybe there are a built-in Java functions:

Although inverting colors near gray will not make much difference.

I'll see what I can do

My idea would be to calculate the contrast with the background colour, and if necessary darken/lighten the highlight color. Similar calculations should probably enter into the multi-choice mode highlight colour.

Do I smell here some nice baking? ;-)

Not quite yet unfortunately.

I am assuming the test version worked.
If not, please leave a comment.
