High-light color too dark in GeomtryGraph/Outliner window on MacOS.

[tkbd]

Hi!,Write down what I noticed during use Wings3D in MacOS.
A dark background is always highlighted when I toggle click these icons.
The color of the icon is also dark, so it's hard to tell what the state.
I've been clicking too many times and not getting what I expected.

And,There is little difference between the lock icon
and the background, making it difficult to distinguish.

I would like it to be cutoize to change the highlight-background color, or change to the white icon set.

Below image are the current status and suggestions.
